IR2175SPBF Overview
The IR2175 is a 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 to enable the high bandwidth signal processing.
