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.
