400 kHz, High Accuracy Current Sensor with Pin-Selectable Gains and Adjustable Overcurrent Fast Fault in SOICW-16 Package
Product Overview
The ACS37002 is a fully integrated Hall-effect current sensor designed for high-accuracy current monitoring. It features factory-trimmed precision, differential sensing for immunity to external magnetic fields, and a robust, isolated SOICW-16 package. The device offers externally configurable functional features, including four adjustable sensitivities and current ranges via 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, high-speed current monitoring, and precise current measurement across a wide operating temperature range.
