Part Number: UCC21750QDWEVM-054 Dear team,
If SiC is removed, What is proper operation of GATE_HS and DESAT pin status?
- IN- : GND
- IN+ : 10KHz PWM
Above input condition, Output is always High with FLT signal. Is it normal operation? Please let me know…
Hi Damith,
Thats right, IN+ and IN- are expected to have VCC/GND wrt to GND, not a differential signal between them.
It is best to use differential to single ended option. We have such implementation as a reference design in the following EVM, you can…

Please note that the critical signaly for this issue are most likely the SPI, not the PWM. Please review the SPI signals and share the…
