Description
The IR2118 is a high voltage, high speed power
MOSFET and IGBT driver. Proprietary HVIC and
latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is
compatible with standard CMOS outputs. The output driver features a high pulse current buffer stage
designed for minimum cross-conduction. The floating channel can be used to drive an N-channel power
MOSFET or IGBT in the high or low side configuration which operates up to 600 volts.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The Ther mal Resistance and Power Dissipation ratings are measured
under board mounted and still air conditions. Additional information is shown in Figures 5 through 8.
