Product Overview

The Allegro ACS37600 is a high-precision, programmable linear Hall-effect sensor IC designed for core-based current sensing applications. It offers industry-leading noise performance, user-programmable bandwidth up to 400 kHz, and a very fast response time (<1.25 s typ.). The device features a precise, low-offset, chopper-stabilized Hall-effect front end that converts magnetic flux into a proportional voltage. Its wide sensing range and user-programmable sensitivity and offset enable flexibility for current sensor modules ranging from <20 a to>1000 A. The ACS37600 includes a user-programmable bidirectional reference voltage pin (VREF) for easy interfacing with ADCs and a user-programmable overcurrent fault (OCF) pin with a 1.5 s response time for fast protection. Ideal for industrial, commercial, and communications applications including current sensing modules, solar systems, motor control, UPS, smart fuses, and power supplies.
