Vishay expands SiC Schottky diode portfolio

EDN Network - Thu, 02/06/2025 - 21:22

Vishay has launched 16 SiC Schottky diodes with 650-V and 1200-V ratings in SOT-227 packages, enhancing efficiency in high-frequency applications. The devices offer, according to the manufacturer, the best trade-off between capacitive charge (QC) and forward voltage drop in their class.

The recently released components include dual diodes in parallel configuration with total forward current ratings ranging from 40 A to 240 A, along with single-phase bridge devices rated at 50 A and 90 A. The diodes feature a forward voltage drop as low as 1.36 V, reducing conduction losses and improving efficiency. They also offer better reverse recovery parameters than Si-based diodes, with virtually no recovery tail.

The SOT-227 package aids efficiency through improved thermal management and reduced parasitic inductance and resistance. The diodes’ low QC down to 56 nC enables high-speed switching, while their industry-standard package provides a drop-in replacement for competing solutions.

Samples and production quantities of the SiC Schottky diodes are available now, with lead times of 18 weeks. To access the datasheets for the dual-diode and single-phase bridge devices, click here.

PMIC extends primary battery operating time

EDN Network - Thu, 02/06/2025 - 21:22

Integrating an efficient boost regulator, the nPM2100 PMIC from Nordic Semiconductor prolongs the life of primary non-rechargeable batteries. Along with a range of energy-saving features, the device ensures that the full charge is used before the cell is discarded.

Powered by an input voltage range of 0.7 V to 3.4 V, the nPM2100’s boost regulator provides an output voltage from 1.8 V to 3.3 V, with a maximum current of 150 mA. It also drives a load switch/LDO, supplying up to 50 mA across an output range of 0.8 V to 3.0 V. The regulator features a quiescent current of 150 nA, with power conversion efficiency of up to 95% at 50 mA and 90.5% at 10 µA.

The nPM2100 manages the power supply for low-power SoCs and MCUs, including Nordic’s nRF52, nRF53, and nRF54 series of wireless multiprotocol devices. Configured via an I2C-compatible two-wire interface, it provides easy access to advanced functions such as ship mode and battery fuel gauging. Additionally, the PMIC furnishes two GPIOs that can be repurposed for time-critical control functions, offering an alternative to serial communication.

Ship mode supports a 35-nA sleep current with multiple wakeup options, including a break-to-wake function that allows a buttonless product to wake from ship mode when an electrical connection is broken. The voltage- and temperature-based fuel gauge runs on the host microprocessor, providing accurate battery level measurements and ensuring full access to the battery’s energy.

Samples of the nPM2100 are now available in a 1.9×1.9-mm WLCSP, with additional variants to be offered in 4×4-mm QFN packages. Volume production is expected in the first half of 2025.

Will open-source software come to SDV rescue?

EDN Network - Thu, 02/06/2025 - 15:37

Modern cars’ capture of advanced features for safety, driver assistance, and infotainment is now intrinsically tied to software-defined vehicles (SDVs), which automakers have already accomplished using lower levels of software based on closed-source, proprietary solutions. However, an SDV can be defined in six levels, with a true SDV starting at level three.

Moritz Neukirchner explains these six levels and argues that open-source software will be crucial in realizing proprietary alternatives for SDVs. While acknowledging that design teams have tried and failed to develop safety-centric, Linux-based solutions for automotive, he provides an update on Linux solutions’ recent progress in incorporating safety functionality into SDVs.

Top Stealth Fighter Jets in India

ELE Times - Thu, 02/06/2025 - 13:27

India’s pursuit of advanced stealth fighter technology has been a focal point in its defense modernization efforts. As of 2025, the Indian Air Force (IAF) operates a fleet that includes aircraft with varying degrees of stealth capabilities, while ambitious indigenous projects are underway to enhance its aerial prowess.

Current Stealth-Enhanced Aircraft in the IAF

While the IAF does not currently field a fully stealth fifth-generation fighter, it operates several aircraft with stealth features:

  1. Dassault Rafale: India has inducted 36 Rafale fighters, which, although not classified as fifth-generation stealth aircraft, incorporate stealthy design elements and advanced avionics to reduce radar cross-section.
  2. Sukhoi Su-30MKI: The Su-30MKI is a twin-engine multirole air superiority fighter developed by Russia’s Sukhoi and built under license by India’s Hindustan Aeronautics Limited (HAL). While not a stealth aircraft, efforts have been made to reduce its radar signature through various upgrades.
Indigenous Stealth Fighter Development: The AMCA Project

India’s most ambitious endeavor in stealth technology is the development of the Advanced Medium Combat Aircraft (AMCA), a fifth-generation stealth fighter designed to bolster the IAF’s capabilities.

In March 2024, the Cabinet Committee on Security (CCS) approved the full-scale engineering development of the AMCA, allocating over ₹15,000 crore for the creation of five prototypes and a structural test specimen. The Aeronautical Development Agency (ADA) of the Defence Research and Development Organisation (DRDO) is spearheading this project.

Key Features of the AMCA
  • Stealth Design: The AMCA will feature advanced stealth characteristics, including serpentine air intakes, internal weapon bays, radar-absorbing materials, and conformal antennas, all aimed at minimizing its radar cross-section.
  • Supersonic Cruise Capability: The aircraft is expected to achieve supersonic speeds without afterburners, enhancing its operational efficiency and reducing infrared signatures.
  • Advanced Avionics: Integration of sensor fusion, multi-sensor data integration, and an Active Electronically Scanned Array (AESA) radar will provide superior situational awareness and combat capabilities.
Development Timeline and Future Prospects

The first AMCA prototype is slated to roll out within four years from the CCS approval, with its maiden flight anticipated a year thereafter. Comprehensive flight testing and certification processes are expected to culminate in the aircraft’s induction into the IAF by 2035.

The initial two squadrons of the AMCA will be powered by GE-F414 engines, developed in collaboration with a foreign partner. Subsequent variants, designated as AMCA Mark-2, will feature more powerful engines, with potential partners including General Electric, Rolls-Royce, and Safran.

Challenges and Strategic Significance

Developing a fifth-generation stealth fighter presents significant challenges, particularly in mastering stealth technology and advanced avionics. India’s previous attempt with the Kaveri engine project in the 1990s faced hurdles, underscoring the complexity of such endeavors. However, renewed efforts and international collaborations aim to overcome these obstacles.

The successful development and induction of the AMCA will position India among a select group of nations capable of producing advanced stealth fighters, significantly enhancing its air combat capabilities and strategic autonomy.

Conclusion

As of latest, while the Indian Air Force operates aircraft with certain stealth features, the realization of a fully indigenous stealth fighter remains a work in progress. The AMCA project represents a pivotal step toward achieving this goal, reflecting India’s commitment to advancing its defense technology and securing its airspace with homegrown solutions.

Interesting screen connection method

I disassembled this "recalibrateable" Caliper and I was wondering why the LCD came off like this with no clear way for the signals to travel to it, I can only assume this is a very interesting way for them to recalibrate it without having to add more pins/pads.
