IR2171 Datasheet (International Rectifier)

IR2171, LINEAR CURRENT SENSOR

IR2171 is the linear current sensing IC designed for motor drive applications.

It senses the motor phase current through an extenal 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 to
