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.
FEATURES
● Built in high CMRR opto-coupler
(CMR:Typical: 30kV/µs, Min.:15kV/µs)
● Two supply drive topology
● TTL compatible input interface
● Electrical isolation voltage between input
and output with opto-couplers
(Viso=3750VRMS/min)
● Built in short circuit protection circuit with a
pin for fault output
● Soft IGBT turn-off and protection circuit time
reset
● Controlled time detected short circuit
● Switching frequency up to 20kHz
● Pin and characteristic are compatible with
M57962AL
