1200 V, 0.35 A / 0.54 A three-phase gate driver IC IR2238Q with integrated DESAT,
Soft-Off, UVLO, TLTO, deadtime, brake chopper and fault reporting

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 shut
down is predominantly initiated in the event of overcurrent followed by turn-off of all six outputs. A
shutdown input is provided for a customized shut down 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.
