ACS781LLR - High-Precision Linear Hall-Effect-Based Current Sensor

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.

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.
