Feature Comparison

Description

Cross-

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.
