    CYPD3171 - Macbook Pro charging problem

    user_4340301

      Dear Cypress,

      We are developing a powerbank for laptops based on CYPD3171 and EZ-PD Configuration Utility software. We have problem only with Apple Macbook Pro, because, the after cable connection, communication is reseted and charging is interrupted. It is strange, because our device works even with Macbook Air without any problem. Below are logs (text and file from EZ-PD Analyzer Utility) from CY4500, when laptop is connected to powerbank. Can You help us with this problem?

      Best regards

          YatheeshK_36

          Hello,

           

          The sink (Macbook Pro) is requesting for object position 5 (SL# 258) i.e. 20V 3A, after the source capabilities is being advertised the by CCG3PA . Is it the same scenario with the other host PCs as well? Is the CCG3PA externally powered to supply around 60W of power?

          If no, please try removing the last PDO i.e. 20V 3A from source PDO of CCG3PA and try the same.

           

          Best Regards,

          Yatheesh
