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.
