Five more members have joined the likes of NXP, Microchip and Renesas in the ISELED Alliance, which overlooks a system of multi-colour addressable automotive LED tape lighting, built around ICs from Inova Semiconductors. The new companies are: Blue Whale (MCUs), Lextar (automotive lighting), Liteon (LEDs), Technica (communication test and validation), Asteelflash (electronic manufacturing) and YTMicro (MCUs) – bringing the total ...

Rohm has developed four and six channel automotive LED drivers for 5 – 10in+ backlights behind displays and instrument clusters. The parts (table below) include 20,000:1 PWM dimming and dc dimming in a way which “eliminates flickering when changing display brightness from low to high”, according to the company. Switching can be between 200kHz and 2.4MHz, and operation is over ...

MicroSys Electronics has announced an evaluation kit for its system-on-modules with NXP S32G processors – which it aims at headless controllers in vehicle networks for automated driving, for example. The kit is designed as a modular single-board computer, with connections for Flexray (2x), LIN (4x), CAN (16x plus 2x CAN FD) and Ethernet for attaching peripherals. As well as the ...

Autronic has created an 80W dc-dc power supply for on-board railway use, which produces 12V (adjustable) from supplies between 14.4 and 154V, covering “all international on-board voltages from 24V to 110V in a single device”, it said. Dubbed HFBC80-W/Ks, output voltage is adjustable, and devices can be connected in parallel for more current. Efficiency can reach 92%. The units measure ...

Kyocera AVX has added four and five position options to its 5.6mm tall 9176-700 series of insulation displacement wire-to-PCB connectors. The connectors are soldered to the PCB in a tall state then, to terminate, insulated wires are inserted and the top of the connector is permanently pushed down to its final height. All four or five wires have to be ...

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. ...
