General Description

The Allegro ACS781xLR is a fully integrated current sensor linear IC in a new core-less package designed to sense AC and DC currents up to 100 A.

This automotive-grade, low-profile (1.5 mm thick) sensor IC package has a very small footprint.

The Hall sensor technology also incorporates common-mode field rejection to optimize performance in the presence of interfering magnetic fields generated by nearby current carrying conductors.

Overview

ACS781xLR High-Precision Linear Hall-Effect-Based Current Sensor IC with 200 µΩ Current.

Key Features

  • Core-less, micro-sized, 100 A continuous current package.
  • Ultra-low power loss: 200 µΩ internal conductor resistance.
  • Immunity to common-mode field interference.
  • Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range.
  • Industry-leading noise performance through proprietary amplifier and filter design techniques.
  • Integrated shield greatly reduces capacitive coupling from current condu.
