Description
The IR2104(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 ruggedized
monolithic construction. The logic input is compatible with standard CMOS or LSTTL output, down to 3.3V logic.
The output drivers feature a high 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

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
