Part Number: TUSB321AI
Hi,
I am currently designing a usb hub with type C connectors (with the upstream connector more emphasised) as high power need to be delivered to devices connected on downstream.
I have been referring to evaluation board schematics but all I have been looking at are for DFP configurations, and I am slightly confused as to how to route the ID pin from the PD controller TUSB321 with the (active low) enable lines for the Mux HD3SS3212 and the Hot swap TPS25910.
It would be ideal for ID line of the PD controller to enable both mux and hot swap but I am not sure as how to. Maybe a simple fet will do? Nee guidance as to how to route for UFP applications.
Hope to hear from you soon. Please let me know if you need anything else.
Kind Regards,
Heewoon Kim
