Description
The IRS21091 is a high voltage, high speed power
MOSFET and 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 IGBT in
the high-side configuration which operates up to 600 V.
