IR2172 Datasheet (International Rectifier)

IR2172, LINEAR CURRENT SENSOR

IR2172 is the monolithic current sensing IC designed for motor drive applications.

It senses the motor phase current through an external shunt resistor, converts from analog to digital signal, and transfers the signal to the low side.

IR’s proprietary high voltage isolation technology is implemented
