Features
Description
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. IR’s proprietary high voltage isolation tech-
nology 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 fa-
cilitates IGBT short circuit protection. The open-drain
outputs make easy for any interface from 3.3V to 15V. S
