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 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.
