MORNSUN®Hybrid integrated IGBT driver Patent protection RoHS Recommended modules • 600V series IGBT (current ^600A) • 1,200V series IGBT (current ^400A) • 1,700V series IGBT (current ^200A) Applications • General inverter • AC servo drive system • Uninterruptible power supply (UPS) • Electric welding machine FEATURES • Built-in high CMRR opto-coupler (CMR: 30kV/jstyp., 15kV/|js min.) • Built in bi-polar power supply • Input signal compatible with CMOS & TTL level • High-isolation voltage opto-coupler (3750Vrms/min) • Short-circuit protection and output fault function • Soft shut-down and reset timer can be used during over-current fault • Adjustable controlled time for detecting short circuit • Switching frequency up to 40kHz • Drop-in replacement to M57962AL (See compatibility notes) QC962-8A is an integrated hybrid IGBT driver, its main function is to receive the square wave signal from the controller, and convert It into an isolated, amplified gate signal which controls the IGBT's turn-on and turn off cycle, it is a square wave signal through the optocoupier that provides reliable electrical isolation, therefore the control system cannot be affected by the common mode interference caused by IGBT. In addition, the QC962-8A driver can also be used to detect the undersaturated voltage drop of the IGBT collector to quickly identify the IGBT's overcurrent or short circuit state and trigger the protection function, so as to avoid IGBT being burned in the fault conditions, afterwards the controller will issue a warning signal.

MORNSUN* connecting the Ctrip capacitor between pin #2 and #6, however the short-circuit detection time delay must be set to less than 3.5 u S. Please also refer to table 2 below (values for reference only). 4. Compatibility feature This product's basic parameter and function of pin are compatible with M57962AL series, so it can be directly replaced if without special requirements, and alternative use should pay attention to the following points: 1) Relative to the M57962AL product our QC962-8A driver has the added threshold protection regulation function at pin #7. To properly use this...

MORNSl'NDimensions and Recommended Layout THIRD ANGLE PROJECTION I-01M [00.039] 1. For additional information on Product Packaging please refer to www.mornsun-power.com. The Packaging bag number:58230001; 2. The driver must be wired as short as possible to the IGBT module’ s gate and emitter terminals (1m max.); 3. Twisted pair is recommended for the connection of the driver to the gate and emitter of the IGBT; 4. In order to reduce the high peak voltage generated at the collector of the IGBT turn-off, it is recommended to increase the gate resistance appropriately; 5. Pin #3, #9 and #10...
