Description
General part information
IR21844SPBF
IR21844SPBF is a high voltage, high-speed power MOSFET and IGBT half-bridge 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 3.3V logic. The output driver features 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 600V.
