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
