Hybrid Integrated IGBT Driver  
QC841 is a hybrid integrated IGBT driver built-in electrical  
isolation between power devices and control circuits with the high  
CMRR opto-coupler. Short circuit protection is provided by a  
built-in desaturation detector. A fault signal is provided if the short  
circuit protection is activate
