Allegro MicroSystems has announced an ASIL C safety rated magnetic field beased current sensor for electric vehicle power trains and automotive battery management systems. The company “has developed the ACS37601 programmable linear Hall-effect current sensor IC with over-current, over-temperature and self-test capabilities,” it said. The part “is Allegro’s highest-accuracy field current sensor for applications requiring measurement capability greater than 200A”. ...

While the global semiconductor industry is in turmoil these days, one Japanese company is rapidly increasing its presence in the industry, under strong leadership. That company is ABLIC Inc., an analog semiconductor specialist. Its uniqueness stems from the fact that in its early beginnings before it was named ‘ABLIC’, the company’s specialized craftsmanship was born in the semiconductor department of ...

Bostik is aiming at automotive electronics with extensions to its UV-cure-in-place gasket (UV-CIPG) and hot-melt polyurethane reactive (HMPUR) adhesives ranges. They are intended to “serve the needs of designers and manufacturers looking to protect automotive components from heat, liquids, humidity, chemicals and vibrations”, according to the company. The two UV-CIPG products ( AU060R and AU589V) change colour during curing and ...

Rohm has announced a series of 50mA low drop-out linear regulators designed to be connected directly to the vehicle battery circuits without an intermediate regulator. Called BD7xxL05G-C, their inputs operate up to 42V and can survive 45V. The parts are: BD725L05G-C (2.5Vout, 3.5Vin min), BD730L05G-C (3.0Vout, 3.5Vin min), BD733L05G-C (3.3Vout, 3.8Vin min) and BD750L05G-C (5.0Vout, 5.6Vin min). Output voltages are ...

Fraunhofer Institute for Microelectronic Circuits and Systems IMS has had a version of its 32bit AIRisc RISC-V microcontroller intellectual property certified by by TÜV SGS to the ISO 26262 ASIL-D automotive safety standard. Called AIRisc-Safety, it can now be licensed from the organisation, which also offers customised versions for asic and FPGA integration. “Certification means that industrial customers directly receive a ...

Toshiba has introduced a brushless dc motor driver that supports ASIL-D for functional safety in vehicles. Designed in accordance with ISO 26262 (2nd edition) and AEC-Q100-qualified, TB9083FTG is aimed at electric power steering, electric braking and shift-by-wire transmissions. “A built-in fail-safe safety relay pre-driver complements the three-phase pre-driver,” according to the company, and the “SPI communication interface features an integrated ...

Aiming at electric vehicle traction inverters, LEM has managed to shrink a 1.5kA current sensor into 29 x 21 x 12mm and 27g. “HSTDR current sensor is significantly more compact than a traditional C-core sensor, making it much easier to be integrated into space-limited inverter boxes,” said LEM. The technology is open-loop Hall effect and the core, integrated bus bar ...

February is definitely the month for automotive high and low-side drivers, proved beyond doubt as Diodes has just followed Rohm, Toshiba and STMicroelectronics with its contribution: a protected 4A (25A pulsed) high-side switch. Called ZXMS81045SPQ, it operates across 5 – 28V (41V abs max) and responds to both 5V and 3.3V logic inputs. Packaging is SO-8 with an exposed heat sinking ...
