Description
Packages
IR2170(S) is the monolithic over current sensing IC de-
signed for motor drive applications. It senses the motor
phase current through an external shunt resistor, de-
tects overcurrent condition, and transfers the signal to
the low side. IR’s proprietary high voltage isolation tech-
nology is implemented to enable the high bandwidth sig-
8-Lead SOIC
nal processing. The dedicated overcurrent trip (OC)
8-Lead PDIP
signal facilitates IGBT short circuit protection. The OC
output pulse width can be programmed by the external resistor and capacitor. The open-drain outputs make easy for
any interface from 3.3V to 15V.
