Description
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 outputsf. 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.

Absolute Maximum Ratings
(tentative)
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.
