Product Summary

The IR2238Q 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. Soft shutdown is predominantly initiated in the event of overcurrent followed by turn-off of all six outputsf. A shutdown input of IR2238Q 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 volts seconds measurement.
