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 across a wide operating range. It features factory trimming for precise measurements without customer programming. The sensor utilizes differential Hall plates to reject common-mode magnetic fields and offers high isolation through its package construction. Available in two package options, MA and LA, each optimized for different performance characteristics (MA for higher isolation, LA for lower noise), the ACS37002 offers flexibility with externally configurable gain settings via two logic pins, allowing for four distinct sensitivities and current ranges. A fast, pin-adjustable overcurrent fault output provides crucial system protection. The device is RoHS compliant and lead-free.
