Hi!
I am designing a smart hub that contains an Upstream USB Type-C port and a Downstream USB Type-C port (and a bunch of other stuff in between), but need to be able to charge through the downstream to the upstream at 100W for a laptop application. The idea is that the upstream will be connected to a MacBook Pro and I want to be able to charge the laptop by connecting a USB Type-C based external power adapter to the downstream USB Type C port. I'm still learning about the connections and how this would be done. Do you have any suggestions for components I can use to do this and perhaps some reference designs/schematics?
I've attached a diagram of what I'm trying to design and have most components selected, just not the DRP controller that allows for charging through an UFP at 100W.
Thanks!
