Description
IR2171/IR2172 are 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. IRs proprietary high voltage iso-
lation technology is implemented to enable the high
bandwidth signal processing. The output format is dis-
crete PWM to eliminate need for the A/D input interface
for the IR2172. The dedicated overcurrent trip (OC) sig-
nal facilitates IGBT short circuit protection. The open-
drain outputs make easy for any interface from 3.3V to
15V.
