    CYPD3177 behavior and questions

    wiae_4532256

      Hi,

       

      We are investigating a design which is a combination of cypress FX3 and CYPD3177.

       

      As i understand from the knowledge base is that currently CYPD3177 does not support changing voltage/sink (PPS).

      So we have to request the highest power needed from the beginning. Is that correct?

      The FX3 can then read out the negotiated power.

      I guess if the FX3 would afterwards change the power contract, the VBUS_FET_EN pin goes low and everything renegotiates from the start

       

      If we want to make voltage and current dependable upon the application (run-time), we need to move to the CCG3PA?

       

      Thanks

      Wim
