Product Description
Product Overview
The ACS37002 is a fully integrated Hall-effect current sensor designed for high accuracy and fast response 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 MA and LA package variants, optimized for isolation and low noise respectively, the ACS37002 features externally configurable gain settings via logic pins, enabling four distinct sensitivities and current ranges. A fast overcurrent fault output provides system protection with a pin-adjustable threshold. The device is RoHS compliant and lead-free. Applications include fast control loops and high-speed current monitoring.
