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.
