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