Allegro MicroSystems Europe has added a new generation of high bandwidth current sensor ICs to their existing family of devices. The Allegro ACS732 and ACS733 current sensor ICs provide a compact, fast, and accurate solution for measuring high-frequency currents in DC/DC converters and other switching power applications. These devices are the first 1 MHz offerings from Allegro to offer 3600 VRMS galvanic isolation ratings. The current sensor ICs are Hall-effect-based and include user-configurable overcurrent fault detection. These features make them ideally suited for high-frequency transformer and current transformer replacement in applications running at high voltages. The ACS732 and ACS733 are suitable for all markets, including automotive, industrial, commercial, and communications systems.
