Part Number: HD3SS3220
Dear expert,
We now use HD3SS3220 to design a DRP Type-C port, from datasheet,the VDD5 is only for VCONN power supply, but it must be powered always,otherwise the usb ID detection cannot work.
Due to we connect two enable pins together(VBUS BOOST and VCONN BOOST), if keep VDD5 on, the VBUS is also on, then it detects as UFP, and cannot use DFP. I attached the schematic,
could you help review it? Thanks! (Please visit the site to view this file)
