The IRS21851 is a high voltage, high speed power MOSFET and IGBT single high-side driver with propagation delay matched output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The floating logic input is compatible with standard CMOS or LSTTL output, down to 3.3 V logic and can be operated up to 600 V above the ground. 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 600 V.
