ACS723LLCTR-40AB-T Description

Short technical summary and product information.

The Allegro ACS723LLCTR-40AB-T is an economical and precise Hall Effect current sensor IC suitable for AC or DC current sensing in industrial, commercial, and communications systems. Its small 8-SOIC package is ideal for space-constrained applications, reducing board area and costs.

 

This sensor IC offers a current range of 40A with a sensitivity of 50mV/A and operates at 5V. It provides bidirectional, ratiometric voltage output with an accuracy of ±3% and linearity of ±1%. The device supports frequencies from DC up to 80kHz with a response time of 5µs.

 

Key features include galvanic isolation, a low-offset linear Hall sensor circuit, and patented digital temperature compensation for accurate performance over temperature. The internal resistance of the conductive path is a typical 0.65 mΩ, ensuring low power loss. The ACS723LLCTR-40AB-T is mounted via surface mount technology.

 

Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. Note that this device is classified as NOT FOR NEW DESIGN and is restricted to existing customer applications.
