Stackpole’s RNCU 1206 thin film chip resistors can handle up to 1W and offer tolerances down to 0.1% and temperature coefficients down to 10ppm/°C. The AEC compliant parts have “excellent electrical and environmental stability, showing minimal resistance shifts over most industry standard tests and are anti-sulphur per ASTM-B-809-95 with shifts less than 1%”, according to the company. They are also ...

Automotive appears to be about the only bright spot in the semiconductor market for 2023., says Seniconductor Intelligence. Forecasts for the overall semiconductor market range from a decline of 4% to a decline of 20%. Semiconductor companies generally have bleak outlooks for the start of 2023, citing excess inventories and weak end market demand. The chart below shows annual unit ...

LEM has created a current sensor specifically for Coulomb counting in electric vehicles. CAB 1500 is an automotive grade open-loop flux-gate transducer, intended to comply with ISO 26262 ASIL C functional safety. Range is ±1.5kA and the sensor is compatible with 800V applications to IEC 60664-1. Galvanic isolation is up to 2.5kV, and total error over -40 to +85° is ...

Ahead of today’s vote on the EU’s ban on the sale of new ICE cars after 2035, the EU is reported to have bowed to pressure from Germany to allow an exception in the case of ICE cars using synthetic fuels. “We have found an agreement with Germany on the future of e-fuels in cars,” says EU vp Frans Timmermans,”we will ...

Diodes has introduced AP7387Q, an LDO linear voltage regulator with a 5V to 60V input range and typically 700mV at a 100mA output current. “Thanks to its wide input voltage, the AP7387Q meets the load dump specifications of 12V internal combustion engine vehicles such as cars and 24V combustion engine vehicles such as buses, coaches, and trucks”, the company said. ...

Premo has releases an integrated wound component package for automotive on-board LLC chargers rated up to 11kW. BCBM-11KW-004 combines 14:15 transformers and resonance inductors for three 3.6kW phases, taking in 400V and delivering 240-460V (<14.7Arms) when switched between 98 and 150kHz. The enclosure is 87(+lugs) x 38(+pins) x 158mm, and the parts inside are encapsulated. “The usage of specific thermal conductive ...

Timing devices provide a mission-critical function in automotive systems. Even if a component or system goes awry, EMS clocking signals must continue operating without fail, says Etienne Winkelmuller, of SiTime. Vehicles are designed to work reliably for many years while operating in harsh conditions. If a component or system malfunctions, the vehicle is still expected to operate safely and reliably ...

Power Integrations is aiming at industrial and automotive power supplies up to 100W, by building 900V GaN transistors into its InnoSwitch3 fly-back switcher family – something it announced at APEC in Florida. Previously 750V was the highest rating amongst the GaN members of this family. There are two product lines now with 900V gallium nitride options: The AEC-Q100-qualified InnoSwitch3-AQ family ...

San Jose based Pre-Switch is reporting 98.5% efficiency at 5% load from its 800Vin ‘CleanWave2’ prototype inverter. Peak efficiency is 99.57%. It is a 100kHz forced-resonant, soft-switching inverter, controlled by an AI algorithm (more on the technology here). “Over a year ago we announced peak efficiency of over 99%. Since that time, we have been improving our AI algorithm to ...

Car part maker Continental has been speaking about its next-generation modular vehicle electrical-electronic architecture. “The growing variety of vehicle functions requires more and more computing power and increasingly complex software applications,” said the company’s CTO Gilles Mabire. “Continental’s new architecture is paving the way for the software-defined vehicle.” Dubbed ZCU, it will be server-based, with central high-performance computers and a ...
