Infineon  is in volume production of its  OptiMOS 7 40V MOSFET family for automotive applications and they can be ordered in August. They combine 300 mm thin-wafer technology with innovative packaging and are  suitable for standard and future automotive 40V MOSFET applications, such as electric power steering, braking systems, disconnect switches new zone architectures. OptiMOS 7 is also aiming at ...

Premo has released a four-phase toroidal common-mode choke for EMC noise suppression in electric vehicle on-board chargers up to 22kW. 4CMCN065R0-32H measures 59mm in diameter, 41.5mm (plus pins) high and ~200g, and is nominally rated at 32A. All the windings have the same number of turns (8), but the one intended for the neutral of a three-phase mains circuit is ...

STMicroelectronics has introduced automotive-qualified MEMS six-axis inertial-sensing module. ASM330LHB, as it will be known, contains a 3-axis accelerometer and 3-axis gyroscope, and is AEC-Q100 qualified. Used in pairs for fail-safe redundancy, with dedicated companion software, it can be used in functional-safety applications up to ASIL B. “Developed in accordance with the automotive functional-safety standard ISO 26262, the software library has ...

The connected car market is set for strong growth, spurred by government regulations and increased use of in-vehicle safety features (see below). Figure 1 – Technavio has announced its latest market research report titled Global Connected Car Market 2023-2027 As more vehicles become more connected and thus vulnerable to malicious cyber attacks, the importance of managing cyber risk grows. Cyber ...

Infineon has introduced automotive high-side power switches for safety-critical circuits. ‘Load Guard 12V’ dual and single-channel are available with nominal current carrying of 2 or 3A, making four devices in total. Without the host MCU getting involved, a pad is provided (OCT in diagram right) for an RC network that can modify the level and timing of current limitation above ...

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 ...
