3. Interface type used to control external MUX?
4. Is Bill board device class supported?
5. Apart from TPS6598x series are there any other integrated solutions targeting DisplayPort Alternate Mode?

    Hi Kevin,

    1. The main difference between the two devices is that the TPS65981 has the capability of using an external power path in addition to the two internal power paths. The TPS65986  only has the two internal power paths

    2. Yes they do. All Type-C PD controllers need to have the ability to support DP alternate modes.

    3. Both the TPS65981 and the TPS65986 use GPIOs to control an external high speed MUX

    4. Yes

    5. No, our USB Type-C PD controllers (TPS65981, TPS65982, TPS65986) are the only integrated solutions for alternate modes as they are required to support them per the USB Type-C PD spec

    6. Not really. Both can accomplish the same thing. The TPS65981 has the external power path while the TPS65986 has a few more available GPIOs to use and configure.
