Hello,
We're working on updating our gate driver design for our three-phase two-level SiC inverter to utilize the UCC14140-Q1 and I had a question about paralleling the inputs and common-mode provisions. We previously used…
Part Number: UCC14140-Q1 Hi expert,
I see that there are a lot of VEE pins for high current return path.
But why dont we have equal VDD pins for high current outward path?
Thanks for explaination
