Proprietary HVIC 2183 Internal 400 COM HIN/LIN yes 180/220 21834 Program 400-5000 VSS/COM and latch immune CMOS technolo2184 Internal 400 COM IN/SD yes 680/270 gies enable ruggedized monolithic 21844 Program 400-5000 VSS/COM 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 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.
