Typical Applications

Packaging

AEC-Q100 Grade 1 qualified
Typical of 2.5 μs output response time
5 V supply operation
Ultra-low power loss: 100 μΩ internal conductor resistance
Reinforced galvanic isolation allows use in economical, high-side current sensing in high-voltage systems
4800 Vrms dielectric strength certified under UL60950-1
Industry-leading noise performance with greatly improved bandwidth 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
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
Output voltage proportional to AC or DC currents
Factory-trimmed for accuracy
Extremely stable output offset voltage

Any High Accuracy Current Sensing Apps requiring >50A (continuous), 2.5μs response time AND high isolation.

This sensor is provided in an Allegro custom CB package offering a very small form footprint, lower ICC and higher accuracy over current sensor modules offered by competing solutions. The ACS772 has a 2.5μs response time, which is the fastest response time IC ever offered in the custom Allegro CB package.
