IR2277S Datasheet (International Rectifier)

IR2277S, Phase Current Sensor IC

IR2177/IR2277 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 s
