Pickering Interfaces will be showing its BMS (battery management system) test demonstration at Battery Tech Expo at Silverstone. “With increasing adoption of electric vehicles, one significant challenge to be tackled is the effective and validation of BMS,” said Pickering simulation product manager Paul Bovingdon. “Using modular, PXI-based switch and simulation modules offers advantages, including flexibility to optimise the test system ...

For Li-ion battery packs up to 25V, STMicroelectronics has introduced an IC for monitoring, balancing and protection, aiming at cordless power tools, back-up energy storage and medical devices. Called L9961, its “built-in features include a dual pre-driver for controlling battery-pack safety relays, which can be programmed for high-side and low-side connection”, said ST. “An embedded non-volatile memory for configuration data ...

Analog Devices has had its wirelessly-linked electric vehicle battery management systems certified to the new ISO/SAE 21434 standard for whole-life cyber-security risk management. It is “the highest standard of automotive cybersecurity engineering and management”, according to ADI, managing security “from concept, product development and production, to operation, maintenance, and decommissioning of electrical and electronic systems.” The company’s wireless battery manager ...

Renesas’s ISL91301B power management IC (PMIC) has been designed into Google’s Coral products. They include the Mini PCIe Accelerator, M.2 Accelerator A+E Key, M.2 Accelerator B+M Key, and system-on-module (SoM). Google Coral integrates into processes at any scale, helping designers employ artificial intelligence (AI) in several industries. The ISL91301B PMIC is designed for low power edge AI processors. It has ...

Low clamping voltage, high surge transient voltage suppressors (TVS) from Alpha and Omega Semiconductor (AOS) are designed for Vbus protection. The AOZ8621UNI series of six TVS are suitable for USB Type-C Power Delivery (PD), in laptops and smartphones and any application using the PD protocol that can deliver up to 100W. The series covers a reverse working voltage (VRWM) range ...

  On the occasion of its 30th anniversary and the shipment of its four billionth chip, Peregrine Semiconductor has changed its name to pSemi. The Murata company has announced that it will broaden its scope and portfolio to include power management, connected sensors, optical transceivers, antenna tuning and RF front end products. “We’ve challenged the pSemi team to broaden their ...

Spansion is sampling its S6AP412A series of multi-channel DC-to-DC power management ICs (PMICs) and expects to have production volumes available in September starting at $3.60 in volumes of 1,500 units.

Cree has signed a non-exclusive worldwide patent license agreement with Transphorm, providing access to Cree’s family of GaN HEMT and GaN Schottky diode patents for use in the field of power conversion. Before it was best known for lighting LEDs, Cree was known for GaN RF transistors. GaN is shaping up as the material of the future for power conversion ...

The power management specialist had net profit in Q309 of $8.8m, representing 14.8% of revenue compared to $3.3m in Q209. Total cash increased in Q309 by $2.9m to stand at $46.4m.

Freescale is looking to its strengths: automotive microcontrollers, power management, sensors, communications processors for networking, and broadband and Internet access, Rich Beyer, Chairman and CEO of Freescale, told the Freescale Technology Forum in Paris this week. A key part of Beyer’s strategy since taking over from Michel Mayer six months ago is to increase the quality levels. “We’re increasing quality by ...
