Nexperia is aiming at protecting high-speed automotive data lines with ESD protection diodes whose capacitance is as low as 0.28pF. With stand-off voltages in the 18 – 32V range and a snap-back characteristic, the AEC-Q101 (automotive) qualified parts are intended to be used close to connectors on boards. The base part number is PESDxxVF1Byy-Q, with xx representing the nominal stand ...

BOS Semiconductors, the South Korean automotive semiconductor startup, is partnering with AI chip specialist Tenstorrent of  Toronto to develop automotive SoCs for automobile application BOS will license Tenstorrent’s AI Tensix core technology to incorporate into BOS Semiconductors’ line of automotive SoCs. Tensix cores are a key element of Tenstorrent’s proprietary AI accelerator chips that are optimized for handling high performance ...

Samsung Electro-Mechanics is aiming at automotive powertrains and safety systems with a 10µF 50V MLCC (multi-layer ceramic capacitor) in 3.2 x 1.6mm 1206 packaging. “Thanks to the application of proprietary ceramic and electrode material atomization, alongside ultra-precision lamination, the company was able to create the 10µF MLCC in 1206 size at 50V rating,” according to the company. “Importantly, the new ...

Aiming at industrial and automotive applications, Diodes has introduced a portfolio of Hall-effect sensors for measuring linear and angular speed and direction. Called AH39xxQ, “they also have a 40V absolute maximum rating, enabling them to safely handle 40V load dumps”, according to the company. “Additionally, -18V of reverse voltage protection guards against incorrect battery connections. For added robustness, the ESD ...

STMicroelectronics has combined two LDOs, a CAN FD transceiver, four PWM-able high-side switches, a watchdog timer and a LIN transceiver into a single automotive-grade power IC. Called SPSB081, its aim is to provide a companion microcontroller with power, two serial interface transceivers, battery-voltage high-side load drivers and power for its peripherals. There are four devices giving 5V or 3.3V from ...

Nexperia has announced a series of 500mA dual bipolar transistors that include base resistors within the 2 x 2 x 0.65mm package – there is a choice of SOT1118 (DFN2020-6) or AEC-Q101 automotive qualified versions in SOT1118D (DFN2020D-6) with wettable flanks. There are 12 devices, giving every combination of: package, NPN+NPN, NPN+PNP or PNP+PNP pairing and 1 or 2.2kΩ series ...

Rutronik has created a smart motor drive evaluation board that combines an Arm Cortex-M0+ MCU with CAN and LIN interfaces – with all of its parts available in automotive-qualified form. Called RDK4 and measuring 48 x 115mm, it is “integrated into Infineon’s ModusToolbox development environment, where software examples are available”, said component distributor Rutronik, which has built the board around ...

The number of  EV charging stations across the world will increase 3x between 2023 and 2026 to 16 million charging points, says TrendForce. By 2026, the number of EV’s will be 96 billion globally setting the vehicle-to-charger ratio at 6:1, a significant drop from the 10:1 ratio in 2021. China has set a goal of achieving a vehicle-to-charger ratio of ...

TDK is aiming at motor testing with the introduction of a power sinking option to 1.7 and 3.4kW models of its Genesys+ 1U-high rack-mount dc power supplies – it is only available for 0-20, 0-30, 0-40, 0-60 or 0-100V output versions. Mounted internally, the sink module (photo below) can absorb 100W continuously and 300W of peak, and fall time can ...

Rohde & Schwarz has introduced 5GHz instantaneous bandwidth front-ends for its automotive radar test set-up. “From the automotive radar perspective, a higher instantaneous bandwidth improves the distance resolution,” the company said. AREG8-81WS (monostatic – single antenna) and AREG8-81WD (bistatic – dual antenna) are for the 76 to 81GHz band and are updates on the 4GHz AREG8-81S and …D. These work ...
