Melexis has added the MLX91231, a shunt-based sensing automotive current sensor for IVT (current, voltage, and temperature) and a digital microcontroller (MCU). The sensor is designed to measure low voltage electronics in vehicle safety systems. It has sensitivity drift error over temperature and lifetime below ±0.25% and a 1.5μV input referred offset drift error over the same conditions. Integrating the ...

Kvaser has created an M.2 slot compatible board that can add four CAN or CAN FD interfaces to a PC or computer Called ‘M.2 PCIe 4xCAN’ (and also 01333-9), it works with PCI Express M.2 slots with B or M keying. It has a main 22 x 80 x 2mm M.2 main board, and four smaller satellite boards (see images) ...

NXP has introduced an intelligent automotive RF IC that can implement automatic vehicle unlocking and short-range in-cabin radar, for example. “This enables OEMs to transform a single UWB-based car access system into a flexible, multi-purpose platform, enabling multiple use cases with the same hardware – for example, OEMs can leverage their secure car access system to also deliver features like ...

Infineon has put 650V mosfet die from its CFD7A portfolio into a surface-mount package with “improved electrical performance over the well-known TO247 through-hole devices, thus enabling efficient energy utilisation in onboard chargers and dc-dc converters”, it said. ‘QDPAK TSC’ is a top-side-cooled package (see images) announced earlier this year and now registered with JEDEC – at the same time it ...

Ford has cut back on the size of an EV battery plant it plans to build in Marshall, Michigan because of weaker demand for EVs than expected. A Ford spokesman stated that EV sales are “not growing at the pace that I think ourselves or the industry had expected.” The original plan had been to build a plant capable of ...

Loctite has created a silicone form-in-place gasket material for automotive electronic enclosures. SI 5972FC is a one-part RTV (room temperature vulcanising) liquid-then-elastomer “with adhesion to a range of metal and plastic surfaces, specifically designed to pass OEM leak or blow-out pressure tests immediately after assembly”, according to the company. “By avoiding the need for curing ovens, Loctite SI 5972FC also ...

The rise in popularity of electric bikes and two-wheelers has brought to focus the need for increased safety requirements. By Vashist Bist and Shashank Wekhande. The choice of battery greatly affects the design of an electric two-wheeler (E2W). Lithium-iron-phosphate (LiFePO4) batteries provide a stable chemical and thermal chemistry, better safety (no thermal runaway) and lower manufacturing cost compared to Li-ion ...

Vox Power has announced a set of conduction-cooled 300W dc-dc converters, for railway and other rugged environment use. Measuring 188.6 x 116 x 25.4, the 33.6 to 160V input range is intended to cover 48, 72, 96 and 110 V railway batteries. Dips to 28.8V can be ridden through covered for 100ms, complete drop-outs for 10ms, and 168V peaks for 1s. ...

Renesas will be using chiplets in its next generation of automotive SoCs, and will add software and tool-compatible automotive microcontrollers. The company revealed this when announcing its 5th generation ‘R-Car’ product range, the first of which will be sampling late next year for cars shipping in 2027. Chiplets are simply die to be used inside multi-die packages. They increase product ...

The  market for Li-ion battery packs for BEV and PHEV will grow to about $180 billion in 2028, with a 16.9% CAGR 22-28, says Yole Developpement. The battery cell supply chain is primarily led by Asian players: China accounting for 57%, with South Korea at 25% and Japan at 7% following. In the coming years, there will be a growing ...
