Durakool is aiming to simplify the interconnections needed for automotive pre-charging and discharging with two separate 1kVdc 120A relays in a single package, which may be switched together or independently. “This double pole contactor is easy to integrate into electric vehicle high-voltage dc motor controllers which have higher pre-charge requirements. It is ideal for use as a pre-charge electric vehicle ...

Rohm is introducing 300mA automotive-grade LDO regulators in a 2.9 x 2.8mm surface-mount package for driver assistance sensors. The BUxxJA3DG-C series can accept input voltages up to 6V and outputs 1.2, 1.8, 2.5, 3.0 or 3.3V depending on version, with drop-out voltage below 370mV (except 500mV for 1.2V version, table below). Rohm pointed out the possibility of regulating a 1.2V ...

Honeywell has created a tough six-degrees-of-freedom inertial measurement unit for heavy-duty and off-road vehicle applications. TARS-IMU, as it is called, comes in two versions: 5V or 9 – 36V, and includes a sensor-fusion algorithm. “The sensor fusion algorithm can be customised for specific vehicle applications via on-board firmware, allowing movement data to be filtered to minimise unwanted noise and vibrations,” ...

With rising automotive battery voltages, Coilcraft has identified a need for PCB-mount inductors to handle the full potential difference, and responded with an 800V rated family of physically-small unshielded through-hole ferrite drum parts. Qualified to AEC-Q200 Grade 3 (-40 to +85°C) and called the RFC0807BV series, they are 8.8mm in diameter, 7.5mm tall and have radial lead length options between ...

SiTime has introduced a  32 kHz oscillator family that provides accurate time keeping for ADAS,  infotainment, instrument clusters and ECUs. To conserve power, electronic subsystems need to be turned on and off frequently and accurately. Since the 32 kHz oscillator (XO) is the time keeping element, and is always-on, its accuracy and power consumption play a significant role in reducing ...

Wi-Fi 6, Bluetooth, Bluetooth Low Energy, Ultra-Wideband, broadcast radio, 802.11p V2X, 4G LTE (or 5G) and GPS have been wrapped in an automotive-grade shell by NXP, which has called the resulting development module ‘OrangeBox’. “OrangeBox is a single, security enhanced, modular development platform that provides a unified interface between the vehicle’s gateway and its wired and wireless technologies,” according to ...

Andes Technology has introduced safety-enhanced RISC-V CPU intellectual property, claiming it to be “the first to certified to be fully compliant with ISO 26262 functional safety standards for the development of automotive applications”. SGS-TÜV Saar audited the core, called N25F-SE, and certified it to ASIL B according to ISO 26262 including Parts 2, 4, 5, 8 and 9, said Andes. ...

IAR Systems is aiming at SiFive’s E6-A and S7-A automotive RISC-V cores with its latest iteration of Embedded Workbench. “E6-A series is aimed at a variety of real-time 32bit applications, from system control to hardware security modules, safety islands and stand-alone in microcontrollers,” according to IAR. “S7-A is a 64bit, high-performance real-time core suited to the needs of modern SoCs ...

Melexis has launched an IC with 21 LED drivers that can power and dim up to 3,000 LEDs. Called MLX81143, it implements CAN-over-UART to control individual LEDs, and the company claims it provides real-time compensation of colour drift caused by environmental changes, and colour-mixing accuracy of less than 1%. The product flyer promises “real-time update of >800 RGB LEDs without ...

GaN Systems has got its GS61008P 100V enhancement mode GaN-on-silicon power transistor designed into a 48V – 12V bidirectional dc-dc converter for mild hybrid vehicles and electric motorcycles. The example design, from Renesas, takes up 46% less PCB area than an earlier all-silicon version, said GaN Systems, due  in part to switching at 500kHz which allowed a move to smaller ...
