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
DSH, DSL input voltage
