Overview

ACHS-7121/7122/7123 Fully Integrated, Hall Effect-Based Linear Current Sensor IC with 3 kVRMS Isolation and Low-Resistance Current Conductor Data Sheet Overview The Broadcom® ACHS-7121/7122/7123 product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing in industrial, commercial, and communications systems.

Each of the ACHS-7121/7122/7123 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die.

Applied current flowing through this copper conduction path generates a magnetic field that the Hall IC converts into a proportional voltage.
