Hybrid Integrated IGBT Driver
QC841 is a hybrid integrated IGBT driver built-in electrical
isolation between power devices and control circuits with the high
CMRR 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)
● Electrical isolation voltage between input and
output with opto-couplers
(Viso=3750VRMS/min)
● Switching frequency up to 20kHz
● Single supply drive topology
● Built in short circuit protection circuit with a
pin for fault output
● Soft IGBT turn-off and protection circuit time
reset
● Pins are compatible with EXB841
