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 (100 to 400 kHz), and a very fast response time (<1.25 s typ.). The device features a wide sensing range, factory-programmed sensitivity and offset over temperature, and user-programmable sensitivity and offset for ferromagnetic core drift compensation. It includes a user-programmable overcurrent fault (OCF) pin with a 1.5 s (typ) response time for fast short-circuit protection and a user-programmable, bidirectional reference voltage pin (VREF) for easy interfacing with 3.3 V and 5 V ADCs. Ideal for industrial, commercial, and communications applications, including current sensing modules, solar systems, motor control, UPS, smart fuses, and power supplies.
