Description
Feature Comparison
The IRS2181/IRS21814 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 technolo-
gies enable ruggedized monolithic
construction. The logic input is com-

patible 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.
