UCC21732QDWEVM-025: Kelvin source terminal of the SiC Mosfet

Varun Bompally

Dear Team,

I would like to use this evaluation board but my mosfet has a kelvin source terminal. I would like to know for which pin I can connect this terminal and use it.

Any information or a schematic in this case would be helpful.

Best regards,

Varun B
