Description
14 Lead SOIC
The IR2109(4)(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 rugge-
8 Lead SOIC
14 Lead PDIP
dized monolithic construction. The logic input is
compatible with standard CMOS or LSTTL output,
down to 3.3V logic. The output drivers feature a high
8 Lead PDIP
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.
