Allegro MicroSystems introduces high-bandwidth current sensor technologies

Allegro MicroSystems announced the launch of its new high-bandwidth current sensors, the ACS37030 and the ACS37032, which enable high-performance power conversion with GaN and SiC technologies in electrified vehicles, clean energy solutions and data center applications. Current high-power-density GaN and SiC FET charging and power infrastructures demand high-speed, low-loss devices to ensure efficiency and reliability. Existing current-sensing solutions have limited operating ranges, as well as added size and weight that result in designs with additional components and larger bills of materials. To address these challenges, Allegro has introduced two high-bandwidth current sensors – the ACS37030 and ACS37032 – designed to provide efficiency and high-performance with reduced design time and board space. They employ a dual signal paths approach, with one path capturing low-frequency and DC current using Hall-effect elements and the other path capturing high-frequency current data through an inductive coil.
