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.
