Allegro MicroSystems has created an isolated gate driver IC for GaN power transistors that has no need for high-side bootstrapping nor the provision of a secondary side drive supply voltage. Instead, a dc-dc converter within AHV85111 produces secondary-side dc power rails – one positive and one negative – to provide gate drive power from a 12V supply (10.8 – 13.2V) ...

Littelfuse has invented an AEC-Q200-qualified temperature monitoring tape for electric vehicle batteries. Branded TTape, it detects local over-heating via thermally sensitive spots spaced along its length, all connected in series. The spots are positive temperature coefficient thermistors. “Distinguishing itself from NTCs [negative temperature coefficient thermistors], the profound advantage of localised cell overheating detection ensures quicker alerts to the battery management ...

Vishay has introduced four ultra-fast 200V rectifier diodes: VS-1EAH02xM3 (1A) VS-2EAH02xM3 (2A), VS-3EAH02xM3 (3A) VS-5EAH02xM3 (5A) “Their low-profile DFN3820A housings provide a space-saving solution with high efficiency, predestined for commercial, industrial and especially automotive applications – they are each available as Vishay Automotive Grade, AEC-Q101 qualified versions,” according to distributor Rutronik, which is stocking the parts. Taking the 3A VS-3EAH02HM3 ...

NXP Semiconductors has announced an extension to its 28nm RF cmos radar one-chip SoC family at CES in Las Vegas. The SAF86xx is the successor to the SAF8500 which is targeted at smart radar sensors. It supports a range of sensor outputs, including object, point cloud-, or range-FFT-level data for smart sensors in today’s architectures and streaming sensors in future ...

TI has introduced a millimetre-wave radar sensor chip which it claims to be the industry’s first for satellite radar architectures, enabling higher levels of autonomy by improving sensor fusion and decision-making in ADAS. In satellite architectures, radar sensors output semi-processed data to a central processor for ADAS decision-making using sensor fusion algorithms, taking advantage of the 360-degree sensor coverage to ...

Lem has introduced a pair of mains residual current monitors for electric vehicle charging that have both digital and analogue outputs. One monitors single-phase live and neutral (CDSR 0.07-TP, photo right), while the other monitors three phases and neutral (CDSR 0.07-NP, photo below). “Because electric vehicles use a high voltage battery, they are also a high-power energy source. This needs ...

12.8 million EVs were sold last year (including BEVs (Battery EVs, PHEVs (Plud-In Hybrid EVs) , and FCVs (Fuel Cell Vehicles), says TrendForce. Regional market sales shares were expected to be 60% in China, 22% in Western Europe, 11% in the US, and 6% in other regions. With China’s subsidies gradually phasing out, the increasing market penetration of NEVs in ...

LG is to demonstrate a customisable cross-domain computer for automated driving and in-vehicle entertainment at CES – aimed at vehicles emerging in 2027. The single electronic module, designed as part of a collaboration with Magna, is intended to support multiple in-vehicle entertainment and information systems as well as automated driving at various ASILs (automotive safety integrity levels). “This scalable solution ...

Vishay has introduced a photovoltaic mosfet gate driver qualified to AEC-Q102 for automotive use. Called VOMDA1271, “the component is available in a SOP-4 housing. The driver is the only one of its kind in this package size with an isolation voltage of 3.750 V [sic] and a typical open-circuit output voltage of 8.5V”, according to component distributor Rutronik, which is ...

Toshiba is in volume production of a photovoltaic output photocoupler with an enhanced open-circuit voltage suitable for gating high-voltage power MOSFETs commonly used in solid-state relays (SSRs). The TLX9910 photocoupler is primarily intended for use within SSR applications in automotive. However, it can equally be used in industrial applications, such as renewable energy. This combination enables high-voltage, high-current switching, which ...
