General Description
The IMP3223 is high voltage, high speed
power MOSFET and IGBT driver with de-
pendent high and low side referenced output
channels. Proprietary HVIC and latch immune
CMOS technologies enable ruggedized mono-
lithic construction. The logic input is compati-
ble with standard CMOS or LSTTL output,
down to 3.3V logic. The output drivers feature a
high pulse current buffer stage designed for
minimum driver cross-conduction. The floating
channel can be used to drive an N-channel
power MOSFET or IGBT in the high side con-
figuration which operates up to 200 volts.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may
occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance
and power dissipation ratings are measured under board mounted and still air conditions.
