IR2170(S) is the monolithic over current sensing IC designed for motor drive applications. It senses the motor phase current through an external shunt resistor, detects overcurrent condition, and transfers the signal to the low side. IR's proprietary high voltage isolation technology is implemented to enable the high bandwidth signal processing. The dedicated overcurrent trip (OC) signal facilitates IGBT short circuit protection. The OC output pulse width can be programmed by the external resistor and capacitor. The open-drain outputs make easy for any interface from 3.3V to 15V.
