    About CCG3PA  PD

    NoAr_1540581

      Hello

       

      They want to use CYPD3171-24LQXQ without PD function and only with Power-SINK. In this case, Please tell me the setting to disable the PD function.
      Or  there any method to disable the PD function?

       

      Best Regards

          Hello,

           

          What is the thing that customer really want to do?

          Even if CCG3PA is PD contracted, CCG3PA can send RDO as 5V/0.1A (0.5 Wattage) at the minimum to the Source.

          Obviously, 5V/1.5A, 5V/3A, etc Sink PDO is also able to set for CCG3PA.

           

          In addition, if the power source is not a PD compliant (does not send Source Capability, etc.), PD negotiation obviously does not start.

           

          If they still would not like to have a PD function on the CCG3PA side, they need to modify the CCG3PA Firmware or request Cypress to develop the specific Firmware.

           

          Best regards,

            Hello Takayama san

             

            I understood.The customer asked because he wants to categorize the product group into two categories: with and without PD.

              Hello Arai-san,

               

              Thank you for letting me know the reason why the customer would like to do it.

              So far, I am not sure why they strongly would like to divide the product group into two categories because CCG3PA can set restrictions as I mentioned to you through the previous interaction.

               

              Anyway, if you have any concern, kindly post here, create another thread, or discuss with local Cypress sales representatives.

               

              Best regards,
