Typical Connection

Description

The IR2108(4)(S) are high voltage, high speed

power MOSFET and IGBT drivers with depen-

dent 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 3.3V 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.
