Allegro MicroSystems Announces Industry’s First ASIL C Safety Rated Field Current Sensor for Electric Vehicle Powertrain Systems

20.04. 2023 | News

Allegro MicroSystems announces the release of samples for the ACS37601, an ASIL C safety rated, high-precision, field current sensor with best-in-class accuracy for traction and auxiliary inverter systems as well as battery management systems (BMS) in electric vehicles (EVs).

Designers of inverter and battery management systems are challenged to achieve higher safety targets based on new Automotive Safety Integrity Level (ASIL) requirements.

To enable customers to meet these new safety requirements, while increasing system efficiency and extending battery life, Allegro has developed the ACS37601 programmable linear Hall-effect current sensor IC with overcurrent, overtemperature, and self-test capabilities. Designed to achieve high accuracy and resolution without compromising bandwidth, the ACS37601 is Allegro’s highest-accuracy field current sensor for applications requiring measurement capability greater than 200 Amperes (more info).
