ACS712ELCTR-20A-T Description

Short technical summary and product information.

The Allegro MicroSystems ACS712ELCTR-20A-T is a highly accurate, galvanically isolated linear current sensor IC. It utilizes the Hall effect principle to provide an output voltage proportional to the primary sampled current, IP, which can be AC or DC.

 

This sensor features a 20A current rating with a sensitivity of 100mV/A and a bidirectional polarization. It offers a low-resistance copper conduction path with a typical resistance of 1.2 mΩ, minimizing power loss. The device operates on a single 5V supply and provides a ratiometric voltage output.

 

Key electrical characteristics include a total output error of ±1.5% at 25°C, a fast 5µs output rise time, and a bandwidth of up to 80kHz. The sensor provides 2.4kVRMS minimum isolation voltage between the primary current path and the secondary pins.

 

Packaged in a compact 8-SOIC package, the ACS712ELCTR-20A-T is designed for surface mount applications. Its low-profile design and robust isolation make it suitable for various industrial, commercial, and communication systems, including motor control, load detection, and overcurrent fault protection.
