ACS780LLR

ACS780xLR High-Precision Linear Hall-Effect-Based Current Sensor IC with 200 µΩ Current Conductor FEATURES AND BENEFITS ▪ 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 conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high-voltage applications ▪ Monolithic Hall IC for high reliability ▪ 4.5 to 5.5 V, single supply operation ▪ 120 kHz typical bandwidth ▪ 3.6 µs output rise time in response to step input current ▪ Output voltage proportional to AC or DC currents ▪ Factory-trimmed for accuracy ▪ Extremely stable quiescent output voltage ▪ AEC-Q100 automotive qualification PACKAGE: 7-pin PSOF package (suffix LR) DESCRIPTION The Allegro ACS780xLR 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...
