    About CYPD3175-24LQXQ spec

    NoAr_1540581

      Hello

       

      I am checking the CCG3PA datasheet for CYPD3175-24LQXQ.

      It is described below.

      Termination Resistor = Rp.

      Role = DFP

       

       

      Since the datasheet is described "Role=DFP". Generaly, I am undrstanding that DFP(=Power Source and Data/Host side)

       

      Q1) However, I am understanding that CYPD3175-24LQXQ can operate  "Power = Power Souce" and  " Data = DRD(Dual Role Data)" . Is it correct ?

       

      Best Regards

      Arai

          Hi Arai-san,

           

          Since CCG3PA is used for Power only applications such as Power adapters and Power banks, the role mentioned in the datasheet is based on Rp and Rd resistor terminations available in different parts. Data role will have to be swapped using DR_SWAP message after PD negotiation to enable UFP data role.

           

          Please consider using CCG3 for Power + Data based designs.

           

          Regards,
