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
