Description

Description The 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 turnoff of all six outputs. A shutdown input of the IR21381Q 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.
