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, high-accuracy Hall-effect current sensor designed for precise current monitoring in a wide range of applications. It features factory-trimmed high accuracy, differential sensing for immunity to external magnetic fields, and a robust, externally configurable design. The sensor offers pin-selectable gain settings for four defined sensitivities and corresponding current ranges, along with a fast overcurrent fault output for system protection. Available in SOICW-16 packages (MA and LA), it provides high isolation and is suitable for applications requiring fast control loops or high-speed current monitoring.
