Diodes has introduced three-pin SOT23 automotive qualified Hall effect magnetic sensing ICs that latch on with one magnetic pole and off with the other. The open-drain output of AH1711Q, AH1712Q and AH1713Q will be switched on when applying a magnetic south pole of sufficient strength near the top of the package (perhaps with north below the package), while a north ...

TTTech Auto and ZettaScale Technology are offering a unified communication platform for the automotive industry called Zetta Auto. Zetta Auto is initially focusing on making Serviced-Oriented Architecture (SOA) communication safe, effective and predictable and looking at unification for cloud-to-MCU communications. The platform delivers the unified integration of  the Data Distribution Service (DDS), Time Sensitive Networking (TSN) and Zenoh (pub/sub/query) protocols. The product ...

MEMS-based sensing devices by Aceinna are available from Avnet, following a global distribution agreement between the two companies. The agreement enables Avnet to sell Aceinna products which include inertial navigation systems (INS), real time kinematic (RTK) solutions, inertial measurement units (IMUs), and current sensors. The MEMS modules are suitable for use in off-road, autonomous, and EV (electric vehicle) automotive markets. ...

Bourns has announced a AEC-Q200 compliant, automotive grade semi-shielded power inductor series that operates across -40 to 150°C. SRN8040HA inductors are constructed using a “silicon-based coating that offers magnetic shielding”, according to the company. They “are designed to release lower magnetic field radiation compared to non-shielded inductors, and are a more cost-efficient alternative to fully shielded ferrite-based inductors”. The data ...

Fibre optic connected PCBs are increasingly part of the requirement for intelligent, technologically advanced electronic systems in modern vehicle design, says Liam Taylor of MicroCare. Whether used for lighting, sensing and safety applications or for autonomous driving capabilities, the vehicles of tomorrow will require vast amounts of real-time data from 5G and emerging 10G networks. It is therefore key to ...

Inertial measurement unit sensors are the automotive sensing devices that enable safety for advanced driver assistance systems and autonomous vehicle operation, says James Fennelly of Aceinna. Inertial measurement unit (IMU) sensors may not attract the same amount of attention as other sensors, such as lidar, radar and cameras, but in many ways IMUs are the critical safety sensor component required ...

Using a safety channel to counter weaknesses in algorithms could steer the automation of commercial vehicles, proposes Eric Richter of BaseLabs. The safe automation of commercial vehicles is a tremendous request from the market. Business cases appear attractive and technical issues seem solvable, yet still, ensuring the safety of such highly automated vehicles is challenging. Designers have to consider the ...

Diodes has created a range of precision current shunt monitors that have a -0.3 to 26V common-mode sense range irrespective of supply voltage, allowing both high-side and low-side measurement – and a reference pin is provided for bi-directional current measurement. Called the ZXCT21xQ family, there are six gain options: 50V/V  ZXCT213Q 75V/V  ZXCT215Q 100V/V  ZXCT214Q 200V/V  ZXCT210Q 500V/V  ZXCT211Q 1kV/V  ...

For vehicle functional-safety applications, STMicroelectronics has combined hot-swap, soft-start and ideal-diode OR-ing in an IC intended to work with a pair of external n-channel mosfets over 4 to 65V. Called STPM801, “the ideal-diode controller drives an external mosfet replacing a Schottky diode conventionally used for reverse-input protection and output-voltage hold-up”, said ST. “When a reverse-voltage event occurs, in case of ...

Current sensor maker LEM now has French national approval for its DCBM 400/600 electric vehicle rapid charger billing meter. “Is the first of its kind to be certified in France by Laboratoire national de métrologie et d’essais, the country’s national laboratory for metrology and testing,” said LEM. “DCBM 400/600 facilitates kWh billing integration into the electric vehicle market for rapid ...
