Description
The IRS2111 is a high voltage, high speed power MOSFET and
IGBT driver with dependent high and low side referenced out-
put 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. In-
ternal 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 V.
