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 DESCRIPTION The Allegro ACS780xLR is a fully integrated current sensor …
