Description  
IR2170 is the monolithic over current sensing IC de-  
signed for motor drive applications. It senses the motor  
phase current through an external shunt resistor, de-  
tects overcurrent condition, and transfers the signal to  
the low side. IR’s proprietary high voltage isolation tech-  
nology is implemented to enable the high bandwidth sig-  
nal 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.
