Allegro MicroSystems, LLC added a new generation of high bandwidth current sensor ICs to their existing family of devices. The Allegro's 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 a high-frequency transformer and current transformer replacement in applications running at high voltages.
