The IRS2186/IRS21864 are high voltage, high speed power MOSFET and IGBT drivers with independent
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 3.3 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.
