Description
The IR2109(4)(S) are high voltage, high speed power
8 Lead SOIC
MOSFET and IGBT drivers with dependent high and
14 Lead PDIP
low side referenced output channels. Proprietary HVIC
and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is
8 Lead PDIP
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.
