Product Overview
The ACS37002 is a fully integrated Hall-effect current sensor designed for high accuracy and robust performance. It features factory-trimmed high accuracy, differential sensing for immunity to external magnetic fields, and a compact SOICW-16 package. The device offers externally configurable functional features, including four adjustable sensitivities and current ranges via two logic gain selection pins. A fast overcurrent fault output provides system protection with a pin-adjustable threshold. The ACS37002 is suitable for applications requiring fast control loops and high-speed current monitoring, operating up to a 400 kHz bandwidth with a typical response time of 1.1 s.
