Apple’s latest product launch event takes flight

EDN Network - Срд, 09/13/2023 - 21:48

Another September…another suite of new AirPods, iPhones and Watches from Apple. Don’t get me wrong: in a world rife with impermanence, there’s something comforting about predictability, no matter how boring it might also be. And at this Tuesday’s event nexus was the most predictable (albeit simultaneously impactful) announcement of all: a decade-plus-one years after unveiling the proprietary Lightning connector for its various mobile devices, replacing the initial and equally-proprietary 30-pin dock connector, the transition to Lightning’s successor has now also begun. This time, though, the heir isn’t proprietary. It’s USB-C.

The switch to USB-C isn’t even remotely a surprise, as I said. The only question in my mind was when it’d start, and now another question has taken its place: how long will it take to complete? After all, more than five years ago the European Union (EU) started making grumbling noises about whether it should standardize charger connections. A bit more than four years later, last October to be exact, the EU followed through on its threat, mandating USB-C usage by the end of 2024. Later that month, Apple publicly acquiesced, admitting that it had no choice but to comply.

With today’s iPhone 15, 15 Plus, 15 Pro and 15 Pro Max, and a cognizant charging case for the tweaked 2nd-gen AirPods Pro, the transition to USB-C has started in earnest. And as usual, the interesting bits (or if you prefer, the devils) are in the details. Since the iPhone 15 and 15 Plus are based on last year’s A16 Bionic SoC, the brains of 2022’s iPhone 14 Pro and 14 Pro Max, they “only” run USB-C at Lightning-compatible USB 2.0 speeds (recall that the connector form factor—USB-A or USB-C, for example—and the bus bandwidth 480 Mbps USB 2.0 or 5-or-higher Gbps USB 3.x—are inherently distinct although they’re often implementation-linked). This year’s A17 Pro (hold that thought) SoC, conversely, contains a full USB 3 controller.

The higher bandwidth potential of the new wired bus generation is particularly resonant for anyone who’s tried transferring long-duration 4K video off a smartphone using comparatively slothlike USB 2/Lightning or Wi-Fi. And Power Delivery (PD) support (assuming it actually works as intended) will be great for passing higher charging voltage-and-current payloads to the phone; the iPhone 15 series implementation is bidirectional, actually, enabling the phone’s battery to even bump up the charge on an Apple Watch or set of AirPods in a pinch. But I was curious to see what exact form this new bus would take, among other reasons due to the system complications it might create. Pre-event rumors had indicated that Apple might have instead branded it as “Thunderbolt 4” which, if true, would have offered the broadest system compatibility: with TB4 and TB3, as well as with TB2 and original Thunderbolt via adapters, and with USB-C and USB generational precursors.

Here’s the thing with USB-C; Apple still supports (although it doesn’t still sell) plenty of Intel-based systems containing only Thunderbolt 3 ports.  And as my own past documented experiences exemplify, USB-C and Thunderbolt 3 aren’t guaranteed to interoperate, in spite of their connector commonality. Intel, for example, sold two different generations of TB3 controllers: “Alpine Ridge” (the chipset in my CalDigit TS3 Plus dock, for example, along with several other TB3 docks and hubs I own) is Thunderbolt-only, while the “Titan Ridge” successor also interoperates with USB-C devices (I plan to elaborate on these differences, along with the additional existing and future enhancements supported by Thunderbolt 4 and just-announced Thunderbolt 5, in an upcoming focused-topic post). If the A17 Pro SoC is really USB-C only, Apple will be facing a notable support burden (albeit decreasing over time, since all newer Apple Silicon-based systems support Thunderbolt 4, therefore also USB-C). That’s why I suspect that although Apple’s marketeers are calling the conector “USB-C” for simplicity’s sake, it’s also Thunderbolt-interoperable.

A few more notes here: Apple’s dropping sales of its Lightning-based MagSafe wireless charging accessories, a curious move considering they still work with still-sold iPhone 14 and 13 variants (RIP iPhone 14 Pro models, along with the iPhone 13 mini). And if you still want to use your Lightning-based charger or other accessory, Apple will happily sell you an overpriced USB-C adapter for it. Bus fixations now satiated, let’s broaden the view and see what else Apple announced this week.

The iPhone 15 family

You already know about the A16 Bionic SoC from last year’s coverage. And you already know about the A16 Pro SoC’s USB controller enhancements. But there’s much more to talk about, of course, beginning with the package-integrated RAM boost from 6 GBytes to 8 GBytes. Last year’s A16 Bionic was Apple’s first chip fabricated on foundry partner TSMC’s 4 nm process. This year, with the A17 Pro, it’s TSMC’s successor 3 nm process, with a commensurate increase in the available transistor budget (from 16 to 19 billion) which Apple has leveraged in various ways:

  • Performance- and power consumption-enhanced microarchitecture CPU cores, albeit with the same counts (2 performance, 4 efficiency) as before
  • An improved neural engine for deep learning inference, claimed up to twice as fast as before, but again with the same core count (16) as before
  • A six-core graphics accelerator with a redesigned shader architecture, claimed capable of up to 20% higher peak performance than before, derived in part from new hardware-accelerated ray tracing support, and
  • Enhanced video and display controllers, now capable of hardware-decoding the AV1 codec (among other things).

About that first-time “Pro” branding for the new SoC …on Monday, Daring Fireball’s John Gruber published an as-usual excellent pre-event summary of how Apple has historically transitioned its smartphone product line each year, and how it’s more recently tweaked the cadence in the era of the “Pro” smartphone tier. Although Apple has previously tweaked smartphone SoCs to come up with iPad variants—from the A12 SoC to the A12X and A12Z, for example—this is the first time I can recall that the company has custom-branded (and high-end branded, to boot: usually you start with a defeatured variant to maximize initial chip yield) a SoC out of the chute. At least two options going forward that I can see:

  • Perhaps next year’s iPhone 16 and 16 Plus will be based on a neutered non-Pro variant of the A17, or
  • Mebbe they’re saving the non-Pro version for the next-gen iPhone SE?

The iPhone 15 and 15 Plus inherit the processing-related enhancements present in the last year’s iPhone 14 Pro and Pro Max, reflective of their SoC commonality.

Apple has also “ditched the notch” previously required to integrate the iPhone 14 and 14 Plus front camera into the display, instead going with the software-generated and sensor-obscuring Dynamic Island toward the top of the display. Speaking of displays, reflective of OLED’s ongoing improvements (and LCD’s ongoing struggle to remain relevant against them), these are capable of up to 2000 nits of brightness when used outdoors. And, speaking of cameras, there are still two rear ones, “main” and “ultra-wide”, the latter still 12 Mpixel in resolution. The former has gotten attention, however; it uses a 48 Mpixel “quad pixel” sensor in combination with computational photography to implement image stabilization and other capabilities, outputting 24 Mpixel images. It also supports not only standard but also 2x optical telephoto modes, the latter generating 12 Mpixel pictures.

Now for the iPhone 15 Pro and Pro Max (again, above and beyond the SoC and RAM updates already covered). First, they switch from stainless steel to lighter-weight titanium-plus-aluminum combo frames:

They incorporate a similar 48 Mpixel main camera as their non-Pro siblings, albeit with slightly larger pixel dimensions for improved low light performance, three focal length options, and the option to capture images in full 48 Mpixel resolution. And, as before, there’s a dedicated 12 Mpixel ultra-wide camera. This time, however, instead of the main camera doing double-duty for telephoto purposes, there’s (again, as with the iPhone 14 Pro generation) a dedicated third 12 Mpixel telephoto camera, this time with 3x optical zoom range in the standard “Pro” and 5x in the “Pro” Max, the latter stretching to a 120 mm focal length. A complicated multi-prism structure enables squeezing this optical feat into a svelte smartphone form factor:

Last, but not least, the previous single-function switch on the side has been swapped out for a multi-function “action” button. Here’s the summary:

Apple Watch Series 9 and Ultra 2

Although Apple claimed via its naming that the SoCs in the Apple Watch Series 6 (using the S6 chip), 7 (S7) and 8 (S8) were different, a lingering rumor (backed up by Wikipedia specs) claimed the contrary: That they were actually the same sliver of silicon (based on the A13 Bionic SoC found in the iPhone 11 series), differentiated only by topside package mark differences, and that Apple focused its watch family evolution efforts instead on display, chassis, interface and other enhancements.

Whether or not previous-generation SoC speculations were true, we definitely have a new chip inside both the Series 9 and Ultra 2 this time. It’s the S9, comprising 5.6B transistors that, among other things, assemble a 30% faster GPU and a 4-core neural engine with twice as fast machine learning (ML) processing as before. The benefits of the GPU—faster on-display animation updates, particularly for high-res screens—are likely already obvious to you. The deep learning inference improvements, while perhaps more obscure at first glance, are IMHO more compelling in their potential.

For one thing, as I’ve discussed in the past, doing deep learning “work” as far out on the “edge” as possible (alternatively stated, as close to the input data being fed to the ML model as possible) is beneficial in several notable ways: it minimizes the processing latency that would otherwise accrue from sending that data elsewhere (to a tethered smartphone, for example, or a “cloud” server) for processing, and it affords ongoing functionality even in the absence of a “tether”. As Apple mentioned on Tuesday, one key way that the company is leveraging the beefed-up on-watch processing capabilities is to locally run Siri inference tasks on voice inputs, allowing for direct health data access right from the watch, for example. Another example is the “sensor fusion” merge of data from the watch’s accelerometer, gyro, and optical heart rate sensor to implement the new “Double tap” gesture that requires no interaction with the touchscreen display whatsoever:

Reminiscent of my earlier comments about OLED advancements, the Series 9 display is twice as bright (2000 nits) as the one in Series 8 predecessors, and it drops down as low as 1 nit for use in dimly lit settings.

The one in the Ultra 2 is even brighter, 3000 nits max to be precise:

And both watches, as well as the entire iPhone 15 family, come with a second-generation ultra-wideband (UWB) transceiver IC for even more accurate location of AirPods-stuck-in-sofa-cushions and other compatible devices. Speaking of AirPods…

Second-gen (plus) AirPods Pro

As previously mentioned, the charging case for the second-generation AirPods Pro earbuds now supports USB-C instead of Lightning.

Curiously, however, Apple doesn’t currently plan to sell the case standalone for use by existing AirPods Pro 2nd-gen owners. The company has also tweaked the design of the earbuds themselves, for improved dust resistance and lossless audio playback compatibility with the upcoming Vision Pro extended-reality headset. Why I wonder, didn’t Apple call them the AirPods Pro 2nd Generation SE? (I jest…sorta…)

The rest of the story

There’s more that I could write about, including Apple’s (but not third parties’) purge of leather cases, watch bands and the like, its carbon-neutral and broader “green” aspirations, and the well-intentioned but cringe-worthy sappy video that accompanied their rollout. But having just passed through the 2,000 word threshold, and mindful of both Aalyia’s wrath (again I jest…totally this time) and her desire for timely publication of my prose, I’ll wrap up here. I encourage and await your thoughts in the comments!

A 50 MHz 50:50-square wave output frequency doubler/quadrupler

EDN Network - Срд, 09/13/2023 - 17:41

On two days in the course of every year, one in March heralding the start of spring and another in September marking the first of fall, the Earth’s axis of rotation aligns perpendicular to the rays of the Sun. These days are the equinoxes and, as the name implies, divide daytime into nominally equal intervals of sunlight and night.

Wow the engineering world with your unique design: Design Ideas Submission Guide

Author of multiple EDN design ideas, Jim McLucas (Mr. Equinox) evidently has a passion and a talent for devising circuits that also divide up time into equal intervals. He has published several clever and innovative design ideas that convert arbitrary waveshapes into 50:50 square waves, thus slicing and dicing the time axis into equal segments. He’s also often included a wide-range frequency doubler functions:

I thought this looked like a fun concept and design challenge, and Jim kindly gave me permission to borrow it and try designing an “equinoctial” circuit of my own. Figure 1 shows the result.

Figure 1 Kibitzer’s version of a McLucas frequency multiplier and square wave generator.

Figure 1’s circuit comprises two almost identical sections: input processor, IP (U1pin1 through A1), and output generator, OG (U1p12 through A2).

The IP is capable of working in either of two modes as selected by jumper J1 or J2. J1 puts the IP into 50:50 mode in which it will accept any duty cycle input and convert it to a symmetrical 50% duty cycle square wave, suitable for frequency doubling by the OG. (This circuit concept is purely Mr. McLucas’s.) J2 puts the IP into frequency-doubling mode in which an input waveshape that’s already 50:50 symmetrical is doubled before input to the OG for net frequency quadrupling.

When frequency doubling J2 is selected, the combination of RC delays (R1C4 in the IP and R8C3 in the OG) and XOR gates (U1) generate high speed pulses (~6 ns width) on each input edge. Hence two pulses per cycle and doubled frequency input to the OG for quadrupled frequency. If J1 is jumpered instead, then R1C4 is bypassed and just one pulse per cycle and an unmultiplied 50:50 square wave is generated by the IP for doubling by the OG.

The hearts of both IP and OG are simple but fast timing loops in which a very fast monostable flip-flop is forced by feedback from an op-amp integrator to generate 50:50 square waves. (Yup. Jim’s idea again.)

My variation on Jim’s basic timing loop concept consists of U3’s two D type flip-flops and the surrounding components, including Schottky switching diodes D1 and D2, current sink transistors Q1 and Q2, and timing capacitors C1 and C2. Because the two loops are essentially identical, let’s talk about the OG loop.

Each timing sequence begins when U1pin8 delivers a clock pulse to U3pin3. U3 is positive-edge-triggered and responds by driving U3pin6 low. This disconnects D2 from timing cap C2 and allows the current sink Q2 to ramp it down toward the switching threshold of U3pin 4 = -SET.

The timing interval thus begun has a duration (~10 ns to 500 µs) determined by Q2’s collector current as controlled in turn by integrator A2. The intent is to force the interval to be accurately 50% of the time between U1pin8 pulses. A2 does this by subtracting the 2.5 V reference developed by the R6R7 voltage divider from the pulse train at U2pin13 and accumulating the averaged difference on feedback capacitor C6. 

If the duty cycle at U2pin13 is <50%, indicating that the U3 timeout is too long, A2’s output will ramp up, increasing Q2’s collector current and C2 ramp rate, thereby making the timeout shorter. If it’s >50%, A2 will ramp down, decreasing IcQ2 and lengthing the timeout. Net result: after a few seconds, U2pin13 will output an accurately 50:50 square wave at 2 or 4 times (depending on J1 J2) the input frequency.

Provided, of course, that said frequency is within the limits of the timing loop.

The high end of said frequency range is mainly limited by the propagation delays of U3, Q2 ,and D2. These sum to about 10 ns (maybe a smidgeon less) and thus limit the max frequency to ~1/(10 ns + 10 ns) = ~1/20 ns = ~50 MHz (or possibly a bit more). The low end is limited by leakage currents (mainly through D2) that can cause C2 to continue to ramp down even when A2 turns Q2 completely off. This leakage can sum to upwards of 10 nA (especially if the diode is warm) and sets a bottom-end interval of ~1 ms and a temperature-dependent minimum frequency of (very) roughly ~1/(1 ms + 1 ms) = ~1/2 ms = ~500 Hz.

OG output is routed through U2pins 6 and 8 and summed by R12 and R13 to produce a convenient 5 Vpp, ~50 Ω output. If no input is provided, the output shuts down at zero volts, preventing overheating of U2.

An additional detail is A3. It serves as an IP duty cycle comparator that holds OG timing loop activity disabled until the IP has converged (or nearly so) on and is producing an accurate 50:50 pulse train. This avoids the possibility of the erratic and persistent confusion of the OG feedback loop, which can occur if it’s allowed to try to converge prematurely.

 It was indeed a fun project—all things being “equal”. Thanks, Jim!

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Nearly 100 submissions have been accepted since his first contribution back in 1974.

Netskope Delivers the Next Evolution in Digital Experience Management for SASE with Proactive DEM

ELE Times - Срд, 09/13/2023 - 09:18

Proactive DEM provides high definition visibility and predictive insights alongside proactive remediation capabilities

Netskope, a leader in Secure Access Service Edge (SASE), today announced the launch of Proactive Digital Experience Management (DEM) for SASE, elevating best practice from the current reactive monitoring tools to proactive user experience management.  Proactive DEM provides experience management capabilities across the entire SASE architecture, including Netskope Intelligent SSE, Netskope Borderless SD-WAN and Netskope NewEdge global infrastructure.

Digital Experience Management technology has become increasingly crucial amid digital business transformation, with organizations seeking to enhance customer experiences and improve employee engagement. With hybrid work and cloud infrastructure now the norm globally, organizations have struggled to ensure consistent and optimized experiences alongside stringent security requirements.

Gartner predicts that “by 2026, at least 60% of I&O leaders will use DEM to measure application, services and endpoint performance from the user’s viewpoint, up from less than 20% in 2021”. However, monitoring applications, services, and networks is only part of a modern DEM experience, and so Netskope Proactive DEM goes beyond observation, providing Machine Learning (ML)-driven functionality to anticipate, and automatically remediate, problems.

Sanjay Beri, CEO and co-founder of Netskope commented; “Ensuring a constantly optimized experience is essential for organizations looking to support the best productivity returns for hybrid workers and modern cloud infrastructure, but monitoring alone is not enough. Customers have told us of the challenges they face managing a multi-vendor cloud ecosystem and so we have yet again innovated beyond industry standards, providing experience management that can both monitor and proactively remediate.”

For issue identification, Netskope Proactive DEM uniquely combines Synthetic Monitoring with Real User monitoring, creating SMART monitoring (Synthetic Monitoring Augmentation for Real Traffic).  This enables full end-to-end ‘hop-by-hop’ visibility of data, and the proactive identification of experience-impacting events. SMART monitoring enables organizations to  anticipate potential events that might impact upon network and application experience.

Auto EV India

While most SASE vendors rely on “gray cloud” infrastructure – built on public cloud – which limits their ability to granularly identify and control any issues, Proactive DEM leverages Netskope NewEdge – the industry’s largest private cloud infrastructure – to deliver 360 visibility and control of end-to-end user experience while providing mitigation of issues, including using various self healing mechanisms, before the user recognises their experience has degraded.

Netskope Proactive DEM capabilities include: Predictive Insights with High Definition Visibility:
  • Introducing SMART Monitoring – Synthetic Monitoring Augmentation for Real Traffic, combining Real User Monitoring (RUM) and Synthetic Transaction Monitoring (STM) to provide organizations a full 360 degree view of users’ digital experiences.
  • Reducing both MTTD (mean time to detection) and MTTR (mean time to resolution) with the correct level of predictive insights and actionable intelligence.
  • Providing true visibility of all four stages of the transaction:
    • Endpoint health and performance monitoring
    • Hop-by-hop view of the connectivity path from user to Netskope
    • True visibility into the performance of all features of the SASE platform including client performance
    • Application response monitoring
  • Identifying anomalies in normal patterns with machine learning modeling, with actionable and tailored alerts helping to reduce alert false positives and streamline network operations processes and response times.
360 Degree Control:
  • Using a combination of proactive and customer triggered remediation, incident impact time can be eliminated or greatly reduced.
  • Providing lightweight Real User Monitoring capabilities helping networking teams gain visibility while removing friction with the endpoint teams.
  • Proactive monitoring of critical business applications provides focus on what matters the most to organizations, helping network operations teams streamline the remediation process, and reducing incident duration.
Proactive Remediation:
  • Proactive remediation – before the user even reports an issue – reduces the burden on help desks and network operations teams.
  • Multi-level routing controls proactively optimize the user experience by identifying the optimum route for critical applications;
    • Proactively switching Netskope NewEdge infrastructure routing decisions, reducing latency and increasing application performance.
    • Selecting the optimum onward path from the Netskope SASE Platform to the application or public cloud provider, routing around external network issues.

Frictionless integration with Netskope Endpoint SD-WAN’s client capability for performance optimization, for applications sensitive to network degradation such as Zoom and Microsoft Teams.

Omdia: Semiconductor industry sees revenue increase for the first time since 2021

ELE Times - Срд, 09/13/2023 - 08:58

After five straight quarters with declining revenue, the semiconductor industry reversed course and increased revenue in 2Q23 according to the latest Omdia’s Competitive Landscape Tracker. The research noted quarterly revenue grew 3.8% to $124.3 bn in this period. This growth is in line with historical patterns for the total semiconductor market, with the second quarter revenue increasing on average of 3.4% from the first quarter (using data from 2002 through 2022). However, growth within semiconductor segments continues to diverge from historical trends. For example, the DRAM market was up 15% in 2Q23 with the historical pattern of 7.5% in the second quarter.


The growth is a welcome sign for the semiconductor industry after the longest period of declines since Omdia began tracking the market in 2002. However, the toll of the shrinking market has reduced the current market considerably, with the semiconductor market by revenue now at 79% of what it was one year ago when total revenue was $160bn in 2Q22. It will take time to return to the revenue levels of late 2021.

NVIDIA led the semiconductor turnaround in 2Q23. Industry wide, semiconductor revenue grew $4.6 bn from the previous quarter, and $2.5bn of that increased quarterly revenue came from NVIDIA alone. The rapid, recent growth in demand for generative AI, a market that NVIDIA dominates, is pushing NVIDIA up the market share rankings.image003

The data processing segment, driven by AI chips into the server space, grew 15% quarter-over-quarter (QoQ) and makes up nearly one-third of semiconductor revenue (31% in 2Q23). The wireless segment (dominated by smartphones) is the second largest segment and declined 3% QoQ as end-demand in this sector continues to be weak. The automotive semiconductor sector continues to grow, up 3.2%.

NVIDIA has led the turnaround, increasing semiconductor revenue 47.5% from the previous quarter. One year ago, NVIDIA was the 9th largest semiconductor company by revenue, at the end of Q2-23 the ranking is third. While NVIDIA was the biggest influence on the growing market, most major firms also contributed to the growth. Of the top ten firms, eight increased semiconductor revenue in 2Q23, illustrating that the turnaround is not limited to one sector of the overall market.

A weird PWM fan controller made with a Pico and some spare parts

A weird PWM fan controller made with a Pico and some spare parts

Kind of got bored so cobbled this together in around 3 hours without really planning it out. The fans are 24V iPPC fans so went overkill with the LDO for the pi (when I tested it on a breadboard I didn't use a heatsink and the LDO sent 24v into the pi after around 2 weeks of use)

I still need to figure out what features I want (there's a pushbutton and a pot which I originally planned on controlling 2 separate PWM channels with) but since the RP2040 is relatively capable I might add more features with double clicking etc.

Nuvoton Releases New Series Automotive Battery Monitoring Chipset

ELE Times - Срд, 09/13/2023 - 08:41

Nuvoton Technology Corporation Japan (NTCJ) today announced the launch of 4th generation of battery monitoring chipset for automotive battery control to measure the voltage and temperature of battery cells and the current of a battery pack with high accuracy.

  1. Simplifying an automotive battery system; one IC manages up to 25 in-series battery cells
  2. Battery Management System (BMS) compliant to ASIL-D; redundant measurement system*1 and bidirectional ring communication*2 support its safety
  3. Offering safety function; a stand-alone chipset which detects abnormalities during car-parking and starts a host microcontroller
  4. Accurate estimation of battery’s State of Charge (SOC*3) and State of Health (SOH*4); ensured by synchronized current and voltage measurements within 10us.
Product details:


With Electric Vehicle (EV) market growth toward a carbon neutral society realization, automobile manufacturers are encouraged to meet demands for a safety improvement of a Lithium-ion battery pack, as well as for a longer EV driving range by enhancing the pack capacity and integration. Furthermore, in order to realize a sustainable society in which mass-produced batteries are reused without being disposed, it is desirable to use batteries for a longer period of time. Not only does BMS secure both high battery capacity and safety, but it also needs a technology that collects various battery parameters such as battery temperature, charging and discharging current to extend battery life.

NTCJ launches 4th generation of battery monitoring chipset, consisting of a battery monitoring IC that accurately measures the voltage and temperature of battery cells, a new line of pack monitoring IC that precisely measures a battery pack’s current and monitors its internal control, and a communication IC that serves as an interface with the ICs above and a microcontroller.

  1. One IC manages up to 25 battery cells in series, simplifying an automotive battery system that generally consists of 100 to 200 in-series battery cells

NTCJ’s currently developed battery monitoring IC can measure up to 25 in-series battery cells which is a 25 percent increase in number compared to the amount of our conventional products. It contributes to the miniaturization and weight reduction of the battery pack since the BMS with higher-capacity and higher-power can be built with less number of components.

  1. Redundancy measurement system and daisy-chain communication make it easier to develop and design a BMS in accordance with ASIL-D of ISO26262

For higher safety, NTCJ introduces a redundancy measurement system into the circuits of the battery monitoring IC and the pack monitoring IC to measure the battery parameter.

A daisy-chain communication among chipset ICs adopts bidirectional ring communication to ensure continuous communication in case abnormalities are detected. This redundancy realizes a system with higher robustness, which suppresses communications disruption in case of failures. This makes it easier for car makers and battery pack manufactures to develop and design automotive BMS achieving Automotive Safety Integrity Level D (ASIL-D) of ISO26262.

  1. Continuous battery monitoring is available in car-parking or microcontroller-in-sleep state to start your system when abnormalities detected

NTCJ’s 4th generation chipset shifts to a low power consumption mode that regularly permits stand-alone monitoring of battery status while the microcontroller is in sleep state. In case abnormalities are detected in the temperature or voltage of the battery cells, the chipset wakes up the microcontroller utilizing the daisy-chain communication to start the BMS.

This function allows to monitor abnormalities of the battery while a car parks or a system sleeps, minimizing system power consumption of batteries. It contributes to a safer system design of EVs which are adaptable to various use scenarios.

  1. Synchronized current and voltage measurement within 10us improves calculation accuracy of internal impedance in battery cells, resulting in high-accuracy estimation of SOC and SOH

The new chipset automatically synchronizes the voltage of battery cells and the current of the battery pack within 10us to calculate the electric power and internal impedance of the battery with higher accuracy, enabling the BMS to precisely estimate SOC and SOH of the battery.
