Description

The IRS2308/IRS23084 are high volt-

age, high speed power MOSFET and

IGBT drivers with dependent high 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.
