General Description

TheAllegro™ACS72981 family of current sensor ICs provides economical and precise solutions forAC or DC current sensing.

A 250 kHz bandwidth makes it ideal for motor control, load detection and management, power supply and DC-to-DC converter control, and inverter control.

The <2 µs response time enables overcurrent fault detection in safety-critical applications.

Overview

ACS72981xLR High-Precision Linear Hall-Effect-Based Current Sensor IC with 200 µΩ Current.

Key Features

  • AEC-Q100 automotive qualification.
  • High-bandwidth 250 kHz analog output.
  • Less than 2 μs output response time.
  • 3.3 V and 5 V supply operation.
  • Ultralow power loss: 200 μΩ internal conductor resistance.
  • Industry-leading noise performance and increased bandwidth through proprietary amplifier and filter design techniques.
  • Greatly improved total output error through digitally programmed and compensated gain and offset over the full opera.
