Description
The IR2111 is a high voltage, high speed power
MOSFET and IGBT driver with dependent high and
low side referenced output channels designed for
half-bridge applications. Proprietary HVIC and latch
immune CMOS technologies enable ruggedized
monolithic construction. Logic input is compatible
with standard CMOS outputs. The output drivers
feature a high pulse current buffer stage designed
for minimum driver cross-conduction. Internal
deadtime is provided to avoid shoot-through in the
output half-bridge.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.
