Internal 500ns dead-time, and programmable up to 5us with one external RDT resistor Lower di/dt gate driver for better noise immunity The dual function DT/SD pin input turns off both channels. VOFFSET IO+/VOUT ton/off (typ.) Dead time 600V max. 120 mA / 250 mA 10 - 20V 680 & 170 ns 500 ns (programmable up to 5uS) Packages 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 8 Lead SOIC 8 Lead PDIP 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.
