Description
The IR2108(4)(S) are high voltage, high speed
power MOSFET and IGBT drivers with depen-
dent high and low side referenced output
channels. Proprietary HVIC and latch immune
CMOS technologies enable ruggedized monolithic construction. The logic input is compatible 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 configuration which operates up to 600 volts.

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