QC962 Hybrid Integrated IGBT Driver QC962 is a hybrid integrated IGBT driver designed for driving N-channel IGBT modules in any gate amplifier application. The device provides the required electrical isolation between input and output with the 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.
