The IR22381Q
The IR22381Q is a high voltage, 3-phase IGBT driver best suited for AC motor drive applications. Integrated
desaturation logic provides all mode of overcurrent protection, including ground fault protection. The sensing
desaturation input is provided by active bias stage to reject noise. Soft shutdown is predominantly initiated in
the event of overcurrent followed by turn-off of all six outputs. A shutdown input is provided for a customized
shutdown function. The DT pin allows external resistor to program the deadtime. Output drivers have
separate turn on/off pins with two stage turn-on output to achieve the desired di/dt switching level of IGBT.
Voltage feedback provides accurate volt x second measurement.

The power module
IRMD22381Q demo board is ECONO2-PIM compatible with
standard pin out.
Important Notice
IRMD22381Q demo board is supplied with a tentative Bill of Material suitable for a 1200V/10A@100C power
module. The BOM presented on page 15 provides a suggestion for the above mentioned power module.
It is strongly recommended to customize the demo board to fit the application requirements for the power
module that has been chosen.
