IR22771S Datasheet Phase Current Sensor IC

Manufacturer: International Rectifier (now Infineon)

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 showing small group delay.
