ACS781KLR - High-Precision Linear Hall-Effect-Based Current Sensor

Download the ACS781KLR datasheet PDF. This datasheet also covers the ACS781LLR variant, as both devices belong to the same high-precision linear hall-effect-based current sensor family and are provided as variant models within a single manufacturer datasheet.

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.

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.
