Product Summary
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. IR2175 proprietary high voltage isolation technology is implemented to enable the high bandwidth signal processing. The output format is discrete PWM to eliminate need for the A/D input interface for the IR2175. The dedicated overcurrent trip (OC) signal facilitates IGBT short circuit protection. The open-drain outputs make easy for any interface from 3.3V to 15V.
