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.
