QC962-8A 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.
