Hi Team,
We received a query from customer asking for the following information about the 9.3.2 Active Output Pull-down in the datasheet. For me to not miss any information from our customer, I will be copying the complete query below.
"From DS:
9.3.2 Active Output Pull-down
The Active output pulldown feature ensures that the IGBT gate OUT is clamped to VEE2 to ensure safe IGBT offstate when the output side is not connected to the power supply.
How does this function sense that the output side is not connected to the power supply? We get this problem when everything else seems ok, and suspect that it could be the BJT buffer "fooling" the driver to think that it is not connected to the IGBT gate."
Looking forward for your kind response.
Regards,
Maynard
