Product Overview

The Allegro ACS732 and ACS733 are next-generation, high-bandwidth Hall-effect-based current sensor ICs designed for accurate measurement of high-frequency AC and DC currents. They offer high isolation, user-configurable overcurrent fault detection, and a low 1 m primary conductor resistance for minimal power loss. These sensors are ideal for high-voltage switching power applications, including DC/DC converters, motor control, load detection, switch-mode power supplies, and overcurrent protection. The compact SOIC-16 wide-body package facilitates easy integration into automotive, industrial, commercial, and communication systems.
