Description

The IR21091(S) are high voltage, high speed power MOSFET and IGBT drivers with dependant high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable rugge-dized monolithic construction. The logic input of the IR21091(S) 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.
