Hi Ivan,
Please follow the steps below to enable UVP in the latest Host SDK project-
- Add VBUS_UVP_ENABLE and set it to 1 in config.h
- Set VBUS_UVP_MODE to VBUS_UVP_MODE_INT_COMP_AUTOCTRL in config.h
- Enable the UVP related parameters in the EZ-PD Configuration utility by creating a new configuration of "Generic" type as shown below. The debounce should ideally be about 10us and threshold should be set to 20 (%) or higher.
Please test it and let us know if there are any issues.
Best Regards,
Sananya

Hello,
UVP feature is usually supported in source-only applications and as mentioned in the User Guide, the UV comparator is unused in the default CCG5 firmware and can be enabled if required. The SCP feature is not supported by the CCG5 hardware and hence cant be enabled in the firmware.
Best Regards,
Sananya
