Top Features

Packaging

Industry-leading total output accuracy achieved with new piecewise linear digital temperature compensation of offset and sensitivity
Industry-leading noise performance through proprietary amplifier and filter design techniques
120 kHz typical bandwidth
4.1 μs output rise time in response to step input current
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
Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range
Small package size, with easy mounting capability
Monolithic Hall IC for high reliability
Ultra-low power loss: 100 μΩ internal conductor resistance
Galvanic isolation allows use in economical, high-side current sensing in high voltage systems
4.5 to 5.5 V, single supply operation
Output voltage proportional to AC or DC currents
Factory-trimmed for accuracy
Extremely stable output offset voltage
Undervoltage lockout for V_CC below specification
AEC-Q100 automotive qualified
UL certified, File No. E316429

The ACS770 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.
