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.

Static Electrical Characteristics
VBIAS (VCC, VBS1,2,3) = 15V and TA = 25oC unless otherwise specified. The VIN, VTH and IIN parameters are refer-
enced to VSS and are applicable to all six channels (HOP/HOQ/HON1,2,3 and LOP/LOQ/LON1,2,3). The VO and IO
parameters are referenced to COM and VS1,2,3 and are applicable to the respective output leads: HO1,2,3 and LO1,2,3.
VDESAT and IDESAT parameters are referenced to COM and VS1,2,3
