IR22771S General Description

IR21771/IR22771 is a high voltage, high speed, single phase current sensor interface for AC motor drive applications. The current is sensed by an external shunt resistor. The IC converts the analog voltage into a time interval through a precise circuit that also performs a very good ripple rejection.
