TPS25751: Questions regarding standalone operation and configuration of TPS25751S

Tool/software:

Hi,

A follow-up to a related question. I would like to confirm the following points regarding the standalone operation of TPS25751S:

1. USBCPD Application Customization Tool usage

   • In Image 1, there is a "DOWNLOAD (TI Cloud Agent Setup)" option. Is this required even when we only need to generate a bin file, or is it only necessary when flashing directly to the device?

     

2. Configuration steps

   • Select TPS25751 (Image 2)

     

   • Choose the TPS25751S configuration (Image 3)

     

   • Enable Advanced Configuration (Image 4) and set:

     • Source PDO: one entry (5V/3A)

     • Add Sink PDOs if needed

     • Enable DRP/DRD and define GPIO assignment

       

   Could you confirm if this procedure is correct? Are there any other mandatory configuration items we should set?

3. File export

   • My understanding is that we can export a bin file, write it to an external EEPROM, and then TPS25751 can run in standalone mode. Is this correct?

   • Also, is it correct that the VIF file is mainly for USB-IF certification purposes and not mandatory for operation?

4. EEPROM programming method

   • Besides programming the EEPROM externally before mounting, is there any tool or method provided to write into an already mounted EEPROM by controlling the write-protect externally?

Thank you very much for your support.
