In the block diagram, there is a resistance between VBUS and PMID, I would like to know if there are any other element. I have also measured the Vdrop between VBUS and PMID, which shows a 0.58V drop from PMID to VBUS, and the circuit is blocked from VBUS to PMID. The detailed circuit between VBUS and PMID is very important for us to choose power use PIN when OTG mode.
