Description

IR2172 is the 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 technol-

ogy is implemented to enable the high bandwidth signal

processing. The output format is discrete PWM to elimi-

nate need for the A/D input interface. The dedicated

overcurrent trip (OC) signal facilitates IGBT short cir-

cuit protection. The OC output pulse can be programmed

by the external resistor and capacitor. The open-drain

outputs make easy for any interface from 3.3V to 15V.
