IR2111 Half Bridge Driver

The IR2111 Half Bridge Driver 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 of IR2111 Half Bridge Driver is compatible with standard CMOS outputs. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Internal dead time 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.
