Allegro ACS711KLCTR-12AB-T Hall Effect Sensor IC Overcurrent Fault 4mA SOIC8

The ACS711KLCTR-12AB-T is a Hall effect sensor that provides a precise solution for AC or DC current sensing in <100V audio, communications systems and white goods. The IC consists of a linear Hall sensor which converts a current-generated magnetic field to a proportional voltage. The output voltage is proportional to AC or DC currents and the sensor has a 3 to 5.5V single supply operation. Typical applications include circuit protection, current monitoring, and motor and inverter control.
