Description

The IR2308(S) are high voltage, high speed power

MOSFET and IGBT drivers with dependent high and

low side referenced output channels. Proprietary HVIC

and latch immune CMOS technologies enable rug-

gedized monolithic construction. The logic input is

compatible with standard CMOS or LSTTL output, down to 3.3V 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 volts.
