QC841 A/1-2008 Page 1 of 2 QC841 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 ABSOLUTE MAXIMUM RATINGS Item Test Conditions Limit Units Supply Voltage* VCC DC 25 V Input Voltage VI Between Pin14 and Pin15 -1~+7 V Photo coupler input current Iin Between Pin14 and Pin15 25 mA Ig on +5 A Output current Ig off Pulse width 2 µs Frequency f=20kHz -5 A Isolation Voltage Viso Sinewave voltage 50Hz/60Hz 1 min. 3750 V Operation Temperature Topr -20~+70 °C Storage Temperature Tstg -40~+125 °C Fault Output Current IFO 20 mA Input Voltage VR1 Pin6 input voltage 50 V Note:Ta=25 °C; unless otherwise specified.
