Description  
The IR2109(4)(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 rugge-  
dized monolithic construction. The logic input is  
compatible with standard CMOS or LSTTL output,  
down to 3.3V logic. The output drivers feature a high  
8 Lead SOIC  
8 Lead PDIP  
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 operates up to 600 volts.
