DESCRIPTION
The ACS732KMA and ACS733KMA are a new generation of high bandwidth current sensor ICs from Allegro™.
These devices provide a compact, fast, and accurate solution for measuring high-frequency currents in DC/DC converters and other switching power applications.
TheACS732 andACS733 offer high isolation, high bandwidth Hall-effect-based current sensing with 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.
TheACS732 andACS733 are suitable for all markets, including automotive, industrial, commercial, and communications systems.
They may be used in motor control, load detection and management, switch-mode power supplies, and overcurrent fault protection applications.
