Hi Sir,
I would like to know whether the PD controller TPS25751DREFR has obtained the USB-IF certification certificate? If you have any, please help provide them to me. Thank you!

Hi,
TPS25751 has been certified by USB-IF for PD3.1.1.8 and PD3.2.1.1 specification. See below for their respective TID:
Thanks and Regards,

Hi Rain,
There are several mismatch in the JSON and VIF configuration which requires your input since it's system dependent. When you created the VIF, did you export it from the USBCPD Application Customization Tool? Please see the table below and let us know your feedback. Many of these VIF/JSON field settings description can be found in the VIF application note linked here: https://www.ti.com/lit/an/slvafz1/slvafz1.pdf?ts=1758058946491
| VIF Config | JSON Field Config | Comments |
| Component - PD_Port_Type set to 0: Consumer Only | Config set to be DRP (5V Source, up to 9V Sink) | JSON config indicates TPS25751 is set to be DRP, why is VIF set to Consumer (Sink) Only? This will cause failures in compliance testing. |
| Component - Port_Battery_Powered set to 'Yes' | Number of Batteries set to 0 | Does your system have a battery in it? If so, the PD JSON needs to be updated accordingly and in the VIF under General PD page, Num_Fixed_Batteries also needs to be updated as well. |
| General PD - Num_Fixed_Batteries and Num_Swappable_Battery_Slots | Number of fixed and swappable batteries set to 0 | Refer to previous comment about batteries. |
| PD Capabilities - USB_Comms_Capable | Enabled in Port Configuration (0x28, 11b) |  |
| PD Capabilities - DR_Swap_To_DFP_Supported | Enabled in Port Control (0x29, 14b) |  |
| PD Capabilities - DR_Swap_To_UFP_Supported | Enabled in Port Control (0x29, 12b) |  |
| PD Capabilities - VCONN_Swap_To_On_Supported | Enabled by default |  |
| PD Capabilities - VCONN_Swap_To_Off_Supported | Enabled by default |  |
| PD Capabilities - Responds_To_Discov_SOP_DFP | Enabled for DRD configs |  |
| SOP Discover ID - USB_VID_SOP | Not set in GUI (refer to Q9) |  |
Here is the VIF generated from the GUI v1.1.1 based on the JSON you provided, quick glance between this version and the one you provided shows drastic differences in the configuration. Please review the mismatch and make the changes accordingly.
