Rugged Relays Go Where Solid-State Switches Fear to Tread

1 week ago | electronicdesign.com | Lee Goldberg

By Lee Goldberg The device was designed for a variety of high-voltage testing and switching applications, including hi-pot testers, high-end cable testers, electric-vehicle charge point testing, solar-energy systems, medical equipment, and high-voltage instrumentation. For more about Pickering's family of high-voltage relays, go here.
Thick-Film Power Resistors Enhance Protection Against Transient Pulses

1 week ago | electronicdesign.com | Lee Goldberg

Vishay Intertechnology expanded its LTO series of thick-film power resistors with a new AEC-Q200-qualified device that delivers higher pulse absorption up to 75 J/0.1 s (30% higher than previous LTO devices) and power dissipation of up to 150 W.
Non-Isolated DCMs Shrink Converter Size Sixfold

1 week ago | electronicdesign.com | Lee Goldberg

By Lee Goldberg Vicor's new non-isolated, regulated DC-DC converter modules (DCMs) are low-profile-package (SM ChiP) devices that offer a 6X reduction in size over a conventional converter. They can be utilized to establish a 12-V bus or used with legacy, downstream point-of-load (PoL) converters. The DCMs are well-suited for bridging 48-V and legacy 12-V power buses in industrial, aerospace and defense, and high-performance-computing (HPC) applications.
PMIC Fits Space-Starved AI, Industrial Computing, Data Center Apps

Leveraging high-performance MPUs and FPGAs, Microchip Technology's MCP16701 power-management integrated circuit (PMIC) is a compact and flexible solution that addresses space-constrained applications.
Advanced Motor Control and Thermal Management Enhance e-Mobility and Automation

1 week ago | electronicdesign.com | Lee Goldberg

Three new solutions developed by Allegro MicroSystems are designed to enhance motor-control and thermal-management performance in e-mobility and industrial automation applications:A89347 Fan Driver ICAllegro's A89347 is an automotive-grade, sensorless sinusoidal three-phase BLDC driver for electric-vehicle (EV) seat- and battery-cooling fans. It offers integrated closed-loop speed control to minimize vibration and audible noise.
Highly Integrated SoC Sets Sights on Automotive Lighting Systems

2 weeks ago | electronicdesign.com | Lee Goldberg

A 12-bit ADC, in combination with an integrated temperature sensor and voltage monitoring, enables automatic compensation for LED color shift due to temperature changes or aging. The integrated LIN transceiver and controller support LIN 2.x and SAE J2602 communication standards, with features such as auto-addressing to simplify network setup. The SoC also supports software updates via the ROM-based UDS bootloader without occupying flash memory.
Energy-Efficient IGBTs and RC-IGBTs Target 400/800-V EV Systems

2 weeks ago | electronicdesign.com | Lee Goldberg

Responding to the growing demand for high-voltage automotive IGBT chips, Infineon Technologies developed a new generation of products: the EDT3 (Electric Drive Train, 3rd generation) chips designed for 400- and 800-V systems, and its RC-IGBT chips tailored specifically for 800-V systems. Both devices are available as bare dies, making it easier for customers to create custom power modules.
MIT and GE Vernova Join Forces to Develop and Scale Sustainable Energy Systems

What you'll learn: MIT continues to expand its research on sustainable energy systems by agreeing to a five-year collaboration with GE Veranova.
Can Nano-Engineered Anodes Boost Li-ion Battery Capacity and Longevity?

2 weeks ago | electronicdesign.com | Lee Goldberg

This synthesis resulted in a well-integrated hybrid composite (rGO/NiFe 2O 4/a-NiO) with enhanced conductivity, making it an efficient anode material for lithium-ion batteries. The hollow structure prevents direct contact between the a-NiO/NiFe 2O 4 nanoparticles and the electrolyte, improving stability. The team then used advanced characterization techniques, such as X-ray diffraction and transmission electron microscopy, to confirm the composite's formation.
Upgraded Open-Source EV Charging Software Stack Supports New and Legacy Apps

2 weeks ago | electronicdesign.com | Lee Goldberg

The Linux Foundation's LF Energy development group released its newest version the LF Energy CitrineOS project, a leading open-source Charging Station Management System (CSMS) software stack-it now supports Open Charge Point Protocol (OCPP) 1.6. This milestone extends CitrineOS's compatibility, expanding the range of electric-vehicle (EV) chargers that can leverage its modular, extensible architecture.
