IR2277S Description

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 showing small group delay.
