UCC5350: Driver high side SiC MOSFET

Hi Jones, 

Thanks for your interest in our driver, my name is Mamadou Diallo from the High Power Drivers applications team. 

UCC5350SB can be used to drive a high-side SiC FET as shown in Figure 4 on the attached app note.

You would require a small transformer based isolated bias to maintain to boot capacitor voltage above the UVLO threshold enabling higher duty cycle operation if necessary.

Having said that, your link didn't attach therefore I could not access details of your application.

If I may, are you interested in this driver in part for the isolation? Or does your application require an isolated gate driver? 

If you provide more details of your application, I can maybe suggest the appropriate driver that will meet your application's needs.

Please let us know if you have additional questions.

Regards,

-Mamadou

 from the AN file, UCC5350 could use to driver up side MOSFET.

thank you very much
