General Description

The Allegro™ ACS770 family of current sensor ICs provides economical and precise solutions forAC or DC current sensing.

Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.

The device consists of a precision, low-offset linear Hall circuit with a copper conduction path located near the die.

Key Features

Industry-leading total output accuracy achieved with new piecewise linear digital temperature compensation of offset and sensitivity.
Industry-leading noise performance through proprietary amplifier and filter design techniques.
120 kHz typical bandwidth.
4.1 µs output rise time in response to step input current.
Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt signals, and prevents offset drift in.
