Description
The IRS2608D(S) is a high voltage, high speed power MOSFET an IGBT driver with dependent 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 3.3 V 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 1GBT in the high side configuration which operates up to
600 V.

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.
