Description

The IRS2308/IRS23084 are high volt-

age, high speed power MOSFET and

IGBT drivers with dependent 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.
