The IRS2004 is a high voltage, high speed power MOSFET and IGBT driver with dependent high- and lowside 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 crossconduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates from 10 V to 200 V.

IRS2011 General Description
Description The IRS2011 is a high power, high speed power MOSFET driver with independent high and low-side referenced output channels, ideal for Audio Class D and DC-DC converter applications. Logic inputs are 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. Propagation delays are matched to simplify use in high frequency applications. The floating channel can be used to drive an Nchannel power MOSFET in the high-side configuration which operates up to 200 V. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.
