In-plane Hall switch rivals MR sensors

EDN Network - Чтв, 09/11/2025 - 18:41

The TMAG5134 in-plane Hall-effect switch from TI offers a cost-effective alternative to magnetoresistive (MR) sensors for position sensing. An integrated magnetic concentrator enables detection of magnetic fields as weak as 1 mT in door and window sensors, home appliances, and personal electronics. Its in-plane sensing adds design flexibility by detecting magnetic fields parallel or horizontal to the PC board.

Designers typically do not consider Hall-effect switches as viable replacements for reed switches or tunnel, anisotropic, and giant MR sensors because of their limited sensitivity. The TMAG5134 overcomes this limitation, delivering higher sensitivity than conventional Hall-effect sensors without the added cost and complexity of MR devices.

Operating from a 1.65-V to 5.5-V supply, the TMAG5134 consumes just 0.6 µA on average. Its magnetic concentrator amplifies the sensor signal, eliminating the need for additional bias current. The device offers flexible magnetic pole detection (omnipolar or dual-unipolar) and is available with push-pull or open-drain outputs, in both active-low and active-high configurations. Magnetic operating points range from 1 mT to 2 mT for versatile position-sensing applications.

Manufactured in TI’s advanced 300-mm fabs, the TMAG5134 is available in production quantities on TI.com.

Between two vendors

EDN Network - Чтв, 09/11/2025 - 17:47

It was a classic stand-off. Vendor number one’s system wasn’t talking to vendor number two’s. What to do? Of course! Blame the customer’s network!

I worked for a TV station that was part of a group run by a common owner. One of the stations in the group used a system known as production automation, which allowed a single operator to control all of the equipment in the control room during newscasts. That would include the video switcher, audio console, camera robotics, video playback, lighting, and graphics generators. The computer system in the newsroom takes the scripts written by reporters and producers, generates a sequence called a rundown, and transmits and updates it in real-time to the automation system.

Do you have a memorable experience solving an engineering problem at work or in your spare time? Tell us your Tale

While performing a major update to one of the systems, communication stopped. Head scratching ensued for a while, and then the two vendors decided the problem must be something in the network that was blocking the IP packets. The station’s engineers pointed out that nothing had been changed in their network, and in any case, there was no internal routing or filtering going on. Not good enough, say the vendors. Prove to us it’s not your fault before we continue. Their advice was to install a copy of Wireshark, analyze the packets, and show us that the path between the systems is clear.

That’s reasonable as far as it goes, but Wireshark is a mighty powerful tool, and it is not for the faint of heart. At the local TV station level, the IT staff generally does not have the expertise needed to fire it up quickly and interpret its results. The station group’s central IT networking folks do, but getting them involved would have taken a good deal of time, and if they had to travel to the site, expense.

I was just a bystander to this. My own station was one of those with the same systems, so I was included in all of the emails flying back and forth. As it happens, not long before this incident, I had written a small one-trick pony Windows utility. All it did was send IP packets from one computer to another via a specific port. As seen in Figure 1, if the path is clear, the receiving computer replies, and the arrows move. Simple as that.

Figure 1 A demonstration of the Windows utility written by the author, sending IP packets from one computer to another via a specific port.

I sent the program to the station’s IT director, and in less than half an hour, he installed it on both systems, checked all of the ports the vendors specified, and found them all clear. With no more finger-pointing at the customer, the vendors had to get to work to find the actual cause of the problem, which turned out not to be network-related.

A few notes about the program. The image shown is just a demonstration, with both ends running on the same machine. In real life, one copy would be on each of two machines on the network, across the room, or across the world. Also, to be honest, I probably spent more time getting the ballistics of the arrow movement looking good than on the rest of the program.

Robert Yankowitz retired as Chief Engineer at a television station in Boston, Massachusetts, where he had worked for 23 years.  Prior to that, he worked for 15 years at a station in Providence, Rhode Island.

AI as the Procurement Copilot: The Next Leap in Semiconductor Supply Chains

ELE Times - Чтв, 09/11/2025 - 15:00

The semiconductor sector remains highly vulnerable to global uncertainty. The consumer electronic to automotive production industry can disrupt due to the single chip shortage. Conventional procurement methods, which depend on manual forecasting and historical trends, often fall short in responding to market volatility, resulting in prolonged lead times and abrupt supply chain breakdown.

Today, artificial intelligence (AI) is increasingly being adopted as a strategic procurement “Copilot”-enhancing rather than replacing human expertise by delivering augmented decision-making that improves agility and precision in decision making.

Why Procurement Needs AI Now

The semiconductor industry has a far more complex procurement function than that in other industries. Lead times for critical components often stretch from 12 to 52 weeks. This complexity stems from wafer fabrication facility(fab), which require months of advance scheduling, while demand can swing dramatically due to market shifts or geopolitical events.

Now, the emphasis is on how AI makes procurement a system that is intelligence-driven and predictive. “AI is moving procurement from hindsight to foresight, enabling leaders to anticipate disruptions before they occur,” according to Deloitte.

AI-driven procurement systems are replacing procurement methods like static supplier scorecards and spreadsheets with dynamic data-driven platform. They can integrate real-time data from wafer fabs, suppliers, logistics providers, and even macroeconomic indicators to provide predictive analytics. This enables procurement leaders to anticipate shortages, rebalance supplier portfolios, and minimize risks, which helps leaders prevent disruption and optimize sourcing strategies before they escalate into crises.

The Procurement Copilot in Action

  1. Predictive Analytics for Lead Time Optimization

In order to generate extremely precise lead time projections, AI-driven systems can process thousands of variables, ranging from silicon wafer availability to equipment maintenance schedules. Procurement teams can use this information to proactively plan production cycles and secure crucial inventories, rather than depending just on supplier updates. According to industry case studies, leading companies have significantly reduced the risk associated with supply bottlenecks by using predictive models to minimize procurement cycle times by up to 20%. Jackie Sturm, Intel’s vice president of supply chain says, “predictive AI is helping us plan weeks ahead instead of reacting days late.”

  1. Supply Chain Resilience Through Risk Mitigation

Supply chains for semiconductors are particularly susceptible to interruption. Global production lines can be stopped by a single sub-supplier. Dashboards with AI capabilities can identify possible hazards early. These include delays in logistics, geopolitical unrest in East Asia, and an excessive reliance on particular wafer fabs.  Procurement professionals may improve supply chain resilience and diversify their sourcing strategy by using AI to simulate “what-if” scenarios. According to McKinsey, “AI-driven procurement enables companies to respond to crises with greater agility than ever before.” It also reduces disruption-related losses by up to 40%.

  1. Wafer Fab Scheduling and Production Alignment

Scheduling for wafer fabs entails thousands of interconnected process steps spanning extremely expensive machinery. AI can greatly improve this scheduling by identifying operational trends that minimize idle time and maximize overall throughput. Procurement leaders can better coordinate upstream suppliers and downstream manufacturing partners by using these data to align sourcing contracts with fab schedules.

  1. Strategic Sourcing and ROI Impact

AI in procurement allows for more intelligent, data-driven investment decisions in addition to cost reduction. AI can find high-value supplier relationships by analyzing the total cost of ownership, which takes into account supplier performance, tariffs, and logistics. Within the first two years of implementing AI in procurement, early adopters have claimed ROI gains of 10–15% due to reduced inventory holding costs and more successful contract negotiations. As Gartner emphasized in its 2024 research, “AI-augmented sourcing is now a boardroom priority, driving measurable returns on resilience and efficiency.”

Global and Indian Context

 AI-enabled procurement systems and automation have been implemented by semiconductor industry leaders such as Taiwan Semiconductor Manufacturing Company (TSMC) and Intel in their wafer fab operations. In order to create a domestic semiconductor ecosystem, the Indian government has allocated around ₹76,000 crores under the Semicon India program, in which procurement would be crucial.  For Indian companies entering chip design, packaging, and fabrication, AI-driven procurement tools can enhance forecasting, supplier management and logistics optimization, helping to achieve bridge gaps in global competitiveness.

Take the proposed Vedanta semiconductor fab in Gujarat as an example. Success for such, s project depends upon on procurement systems capable of handling long lead times for fab equipment, fluctuating global wafer supply, and complex logistics.  An AI- driven procurement Copilot can provide the foresight and agility necessary to mitigate risk and ensure projects remain on schedule despite global uncertainties.

Challenges Ahead

The AI adoption in procurement is not as easy as it seems as it is encountering with several hurdles. In terms of the fragmented supplier network the data quality and availability remain among the major constraints.

For the purpose of smooth integration, many small and medium- sized suppliers lack the digital infrastructure required. Procurement leaders must carefully balance human judgment with AI -driven insights, especially when navigating geopolitical uncertainties or making long-term strategic sourcing choices.

Another significance obstacle is change management. Team in charge of procurement who are used to traditional negotiation methods could be hesitant to depend on    AI- generated insight. Transparent model outputs, explainable decision logic, and a clear demonstration of return on investment(ROI) are necessary to foster trust in AI Copilot.  As stated by Gartner “Responsible AI governance guarantees that AI stays an enabler, rather than a black box, keeping humans informed and accountable.

The Road Ahead

As semiconductor becomes the foundation of the digital economy, procurement is evolving from a cost-centric function to one focused on its ability to build resilience and agility. The procurement teams to move from reactive decision- making to proactive, data- driven strategies with the help of strategic procurement Copilot.  AI enables leader to make decisions with more accuracy and assurance by combining risk mitigation, strategic sourcing, and predictive analytics.

In India, where semiconductor manufacturing identified as a national priority, AI-driven procurement can translate policy goals into industrial capability. Early adopters of AI Copilot in procurement will enhance supply chain resilience and enhance their global competitiveness in the semiconductor value chain.

Exclusive Insights: Design IPs Vs Productization? Raja Manickam at Semicon India 2025 Says Focus on Productization

ELE Times - Чтв, 09/11/2025 - 14:50

“Productizing an IP, to make it into a product, is where the money is,” remarks Raja Manickam, a semiconductor industry veteran with 4 decades of industry experience and Founder & CEO, iVP Semi, in an exclusive interaction with the ELE Times at Semicon India 2025. This is amidst the central government empowering the semiconductor industry through various schemes, including the DLI scheme with a capital outlay of around Rs 1,000 Crore.

Emphasizing his global outlook, Mr. Manickam draws parallels with chip giants to frame India’s semiconductor journey within a larger global vision. He asserts, “Creating IP is not the issue for us at all. The myth is that we need IP to make a product.” Challenging this notion, he stresses that IP alone does not define standards in the semiconductor industry. Instead, he urges India to focus on building stronger pathways to productization, which he believes is key to enabling a complete and sustainable ecosystem.

Focus On Substantial Value Addition

By drawing on examples of global chip brands, he reimagines India’s journey in semiconductors and electronics through a global lens.Product companies make the most money out of the whole value chain and can build globally recognizable brands like NVIDIA or AMD,” he explains. Highlighting how every semiconductor crosses countless stages before becoming part of a final product, he points out that true value lies not just in designing chips but in building strong product companies that can scale globally.

He also refers to his company, iVP Semi, which emphasizes developing tangible products such as DC-DC inverters, relays, solid-state relays, power modules, and powertrains, instead of pursuing an IP-licensing model. iVP Semi reflects a deliberate and measured vision, shaped by Mr. Manickam’s long-standing commitment to fostering homegrown product companies.

With this perspective, he calls attention to the pressing need for a holistic semiconductor ecosystem—one that nurtures both talent and value creation, anchored in a long-term and reliable vision.

Figuring Out the Systems Approach

He says,” To make a chip, they need multiple IPs. They may have one IP or they may not even have an IP,” referring to the chip giants. “But they have figured out how to put all these IPs together and make a product,” he adds, further validating his stance.

In the conversation surrounding Design IPs, he seems to have a certainly different opinion that focuses on realigning India’s semiconductor ambitions towards realizing a systems approach that holds higher potential and can garner substantial and long-term value for the Indian talent and economy, both.

Focus on Startups

With this approach in mind and a quest to see India reach this potential, he urges big companies and corporations to adopt small companies and help them with capital and talent, both to realise this dream. He says,” So, my philosophy is to adopt these guys. But don’t look at it from an ROI,” as the conversation wraps up.

Raja Manickam, an IIT Kharagpur graduate, is a semiconductor veteran who founded Tessolve in 2003, growing it into a 1,000-crore global leader before its acquisition by Hero Electronix. He later served as the first CEO of TATA Electronics OSAT and founded Ponni Tech Consultants in 2023. In 2024, he launched iVP Semi to localize chip production and drive India’s semiconductor self-reliance. His vision is to build a robust ecosystem that attracts global partners to India.

Why Cascading Chipsets and Fusion Testing Define the Next Era of Automotive Radar

ELE Times - Чтв, 09/11/2025 - 10:15

Automotive radar systems have become a cornerstone of advanced driver-assistance systems (ADAS), enabling object detection, collision avoidance, blind-spot monitoring, and adaptive cruise control. As vehicle autonomy advances toward higher SAE levels, radars are evolving with greater resolution, longer range, and multi-object tracking capabilities. But with this leap in performance comes the pressing challenge: how to test these increasingly complex systems with the accuracy and repeatability needed for safe deployment on public roads.

Technology Environment: 24 GHz to 77 GHz and Higher:

The environment of automotive radar is changing quickly. Due to bandwidth constraints and stricter spectrum laws, traditional 24 GHz radars once common for short-range applications like parking assistance and cross-traffic alerts are currently being phased out.

Radars operating at 77 GHz are replacing them as the new norm. They provide a greater bandwidth, longer detection ranges, better range resolution, and more robust interference resistance. For mid- to long-range ADAS features like adaptive cruise control, lane-change assistance, and automated emergency braking, they are therefore essential. However, there is a cost and design complexity trade-off.

At the same time, radar sensing has evolved from 2D to 4D imaging radar. Conventional 2D radars could measure distance and velocity but lacked elevation, limiting object classification in dense traffic. By contrast, 4D imaging radars measure distance, velocity, azimuth, and elevation simultaneously producing LiDAR-like point clouds enriched with Doppler data. This technology thrives in poor weather conditions like fog, rain, or snow, where optical sensors struggle, making it indispensable for L2+ through L4 autonomy.

Radar Test Architecture:

Radar Test Architecture for Automotive Applications: Phase-Coherent Multichannel Signal Generation, LO Distribution, and Parallel Receiver Testing with Automation Flow

This diagram illustrates a radar test setup optimized for automotive radar validation. It begins with multichannel vector signal generators that ensure phase coherence and support cascading for scalable configurations. The signals are routed through an LO distribution divider, feeding synchronized local oscillator signals to multiple vector signal analyzers for parallel receiver testing. At the base, an automation controller manages the test flow, enabling throughput optimization across channels.

Latest Trends in Radar Testing:

As radar performance expands, testing methodologies are transforming as well. Today’s radar testers are not only tasked with validation under ideal conditions but also with simulating real-world unpredictability before vehicles even hit the road.

  1. 4D Radar Simulation

Virtual test environments can replicate rain, snow, fog, and multipath reflections that are impractical to test on real roads. These simulations are vital for developing next-gen 4D radars.

  1. Hardware-in-the-Loop (HiL) Testing

HiL connects real radar hardware with a simulated driving environment. This allows engineers to test radar responses to cars, pedestrians, and traffic scenarios entirely in the lab—reducing cost and speeding up development.

  1. AI-Enhanced Radar Validation

AI plays an increasing role by detecting subtle anomalies in radar signals, generating rare accident-like scenarios, and predicting radar degradation. This accelerates validation cycles compared to manual testing.

  1. Sensor Fusion Testing

Since radars rarely operate alone, test systems now validate how radars integrate with cameras and LiDAR. Ensuring all sensors remain synchronized and error-free is critical to the safety of self-driving systems.

Industry Insights: Keysight Technologies at the Forefront

As automotive radar systems evolve to meet rising demands for higher resolution and precision, Keysight Technologies stands at the forefront of testing innovation. With chipset vendors adopting cascading architectures to boost transmit and receive channel counts, radar complexity is increasing alongside the need for more rigorous and extended test cycles. Natarajan Mahesh from Keysight’s Radar Testing Team highlights this shift as a key challenge in next-gen radar development.

“Automotive radar chipset vendors are looking to increase the transmit and receive channel count to cater to the increasing demand for better resolution using methods such as cascading radar chipsets. The higher channel count of receiver and transmitters will essentially mean more test time.” Natarajan Mahesh, Radar Testing Team, Keysight Technologies

Keysight Technologies is addressing this challenge with specialized solutions that balance complexity with efficiency:

  • Coherent Multichannel Signal Generators – providing compact, phase-aligned outputs with excellent phase noise.
  • Local Oscillator Distribution – delivering stable, low-noise signals for cascading architectures.
  • Simultaneous Multi-Channel Stimulus – enabling parallel receiver testing and cutting down test duration.
  • Radar-Specific Test Automation – supporting MIMO radar, FMCW waveforms, and Doppler emulation.

Keysight also extends its scope into cybersecurity with its SA8710A Automotive Cybersecurity Test Platform, ensuring that radar systems in connected vehicles are validated not just for performance but also for resilience against digital threats.

“Keysight Technologies has solutions for the autonomous vehicle and in-vehicle communication systems, of which radar is one of the most critical sensors.”

Natarajan Mahesh, Radar Testing Team, Keysight Technologies

Future Outlook:

  • Fully Virtualized Validation: AI and physics-based simulations work together to provide nearly comprehensive test coverage prior to in-person trials.
  • 5G-Connected Testbeds: over-the-air (OTA) firmware optimization and cloud-based radar analytics.
  • Automated Test Labs: these robotic devices simulate targets dynamically from various perspectives.
  • 4D radar standardization: frameworks for industry-wide certification that establish consistent performance benchmarks.

Conclusion:

Automotive radar testers are critical enablers of the next wave of ADAS and autonomy. As radars evolve from basic range-speed sensors to high-resolution 4D imaging systems, test platforms must evolve as well becoming simulation-rich, AI-driven, and fusion-aware.

Companies like Keysight Technologies are leading this transformation, ensuring that radar-equipped vehicles perform safely, reliably, and securely under all conditions ultimately paving the way toward fully autonomous driving.

  1. Modular Inverter Architectures

Scalability is key for automakers producing EVs across different segments. Modular inverter platforms allow:

  • Power scaling from 75 kW to 300 kW
  • Reuse of software, control logic, and digital stages
  • Faster time-to-market and lower R&D costs

This flexibility helps OEMs deploy multi-platform strategies, from two-wheelers to heavy-duty trucks, with automotive-grade reliability.

EV Traction Inverter Architecture:

This diagram illustrates how torque commands from the Vehicle Control Unit (VCU) are processed by a safety-optimized microcontroller (Safe MCU), which drives high-voltage SiC FETs through isolated gate drivers. These switches convert DC from the battery into 3-phase AC for the traction motor. Resolver and current sensing provide real-time feedback, enabling precise motor control and efficient bidirectional energy flow.

System-Level Trends:

Beyond materials, traction inverter innovation is increasingly system-driven:

  • Bidirectional Charging & V2G: SiC and GaN enable energy flow back to the grid, turning EVs into mobile storage units
  • Integrated Powertrains: OEMs are combining inverter, motor, and gearbox into unified modules for space and weight savings
  • Cooling Innovations: Double-sided cooling and optimized thermal paths are reducing module size and improving reliability
  • Software-Defined Inverters: Adaptive control algorithms are enhancing efficiency across driving conditions

Industry Spotlight: Infineon Technologies

To understand how traction inverter technology is evolving in the EV sector, Hans Adlkofer, Senior Vice President of Automotive Systems at Infineon Technologies AG, shares his perspective. He explains the technological shifts driving more efficient, compact, and bidirectional inverters, and how these advancements are shaping the future of electric powertrains.

“We can expect even more compact and efficient traction inverter designs. The shift from traditional IGBTs to Silicon Carbide (SiC) is driven by the need for higher performance, reduced size, and increased EV range. Fusion of IGBT and SiC technologies in a single module also optimizes cost-performance. Gallium Nitride (GaN) will further support advanced inverter topologies, including multi-level designs.”

“The transition to SiC and GaN opens the space for innovative module development, such as smaller or optimized cooled modules. Discrete solutions allow very compact inverter designs or integration directly into the motor. This contributes to higher efficiency, lower cost, and increased mileage.”

“Latest SiC and GaN products enable bidirectional charging, supporting intelligent V2G use cases. EVs can now act as mobile energy storage units, creating a more sustainable energy ecosystem and new business models for battery utilization.”

Conclusion:

Traction inverters are no longer functioning solely to change DC to AC traction inverters have effectively become the brain centre of an electric vehicle’s power train. They are changing electric vehicle performance and energy management with wide-band gap semiconductors, AI predictive control, modular system designs, and energy flow that is bidirectional.

As automakers focus on increasing charging speed, boosting range, and developing more intelligent energy systems, traction inverters will be instrumental in the renaissance of electric vehicles.
