ACS722LLCTR-20AB-T Description
The Allegro™ ACS722 current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, commercial, and communications systems. The small package is ideal for space-constrained applications while also saving costs due to reduced board area. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. The ACS722LLCTR-20AB-T consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.
