The ACS37002 is a fully integrated Hall-effect current sensor designed for high accuracy and robust performance in a compact SOICW-16 package. It offers factory-trimmed precision without the need for customer programming, sensing current differentially to reject common-mode magnetic fields. Available in two packages, MA and LA, it provides options optimized for high isolation (MA) or low noise (LA). Key features include a 400 kHz bandwidth, adjustable gain settings via logic pins, and a fast, pin-adjustable overcurrent fault output for system protection. The device is suitable for applications requiring precise current monitoring in fast control loops or high-speed current sensing scenarios.
