Description
The IR22381Q and IR21381Q are 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.

IR22381QPBF/IR21381Q(PbF)
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to VSS, all currents are defined positive into any lead. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.

Note 1: While internal circuitry is operational below the indicated supply voltages, the UV lockout disables the output drivers if the UV
thresholds are not reached.
Note 2: Logic operational for VS from VSS-5V to VSS+600V (IR21381) or 1200V (IR22381). Logic state held for VS from VSS-5V to VSS-
VBS. (Please refer to the Design Tip DT97-3 for more details).
