Product Description

Product Overview

The Allegro ACS37612 is a coreless, high-precision, Hall-effect current sensor IC designed for low-cost AC and DC current sensing solutions. It eliminates the need for external magnetic concentrator cores or shields, making it ideal for applications where hundreds of amps flow through a busbar or PCB trace. The device features differential sensing topology for common-mode stray magnetic field rejection, high isolation, and a fast response time (<2 s typ) for overcurrent fault detection. With a wide ambient operating temperature range (40C to 150C) and AEC-Q100 Grade 0 automotive qualification, it is suitable for harsh environments. The ACS37612 is available in 120 kHz and 240 kHz bandwidth options, making it well-suited for inverter phase current sensing, load detection and management, power supplies, and DC/DC converters. Its compact, low-profile 8-pin TSSOP package ensures suitability for space-constrained applications.
