Features
Typical Application
Description
IC designed for motor drive applications. It senses
the motor phase current through an external shunt
resistor, detects overcurrent condition, and trans-
fers the signal to the low side. IR’s proprietary high
voltage isolation technology is implemented to en-
able the high bandwidth signal processing. The
dedicated overcurrent trip (OC) 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.
(Refer to Lead Assignments for correct pin configuration). This/These diagram(s) show electrical connections only. Please
