DESCRIPTION
The Allegro™ ACS724/5LMC current sensor IC is an economical and precise solution for AC or DC current sensing in industrial, and communication systems. The small package is ideal for space-constrained applications while also saving costs due to reduced board area. Typical applications include solar inverters, DC/DC, electric vehicles on-board chargers, motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.

FEATURES AND BENEFITS
