Please refer to our Application Notes and DesignTips for proper circuit board layout. Description The IRS2184/IRS21844 are high volt- age, high speed power MOSFET and IGBT drivers with dependent high-side and low-side referenced output chan- n els. Pro prie ta ry HVIC an d la tch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with stan- dard 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.
