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 function...
