Top Features

Packaging

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

The ACS780xLR family is lead (Pb) free. All leads are plated with 100% matte tin, and there is no Pb inside the package. The heavy gauge leadframe is made of oxygen-free copper.
