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 field 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 (
