Description
Internal 540ns The IR2308(S) are high voltage, high speed power IN/SD yes Programmable 0.54~5 s MOSFET and IGBT drivers with dependent high and yes HIN/LIN Internal 100ns COM low side referenced output channels. Proprietary HVIC Internal 540ns COM HIN/LIN yes 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 parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
