Packages 14-Lead PDIP IR21844 8-Lead SOIC IR2184S 14-Lead SOIC IR21844S 8-Lead PDIP IR2184 The IR2184(4)(S) are high voltage, high speed power MOSFET and IGBT drivers with dependent high and low side referenced output channels. Pro- prietary HVIC and latch immune CMOS technologies enable rugge- dized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output, down to 3.3V 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 volts.
