CH701W Overview
The CH701W current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, automotive, mercial, and munications systems. The small package is ideal for space-constrained applications while also saving costs due to reduced board area. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.
