Other Parts Discussed in Thread: HD3SS460
Dears,
I use TPS65986 in a tablet computer,but I have troubles now.I use the two devices of TPS65986 and HD3SS460 like Figure 81 in the Specification of TPS65986,and my circuit is a Single-Port tablet computer Application.
1.When I inserted a U disk of USB3.0,the system worked well,but when I inserted a removable disk of USB3.0,no communication between removable disk and tablet computer,and I measured the voltage of VBUS of Type-C at this time,the voltage was pushed down. If this was because removable disk needed more current or some others reasons?
2.When the tablet computer in shutdown state was chargering by Typc-C from a 5V source,at this time the computer closed chargering and the ID pin was pull low if I started the computer,computer recognised the charging source as a slave,so it closed charging.Why did this happen? And I pluged again, the computer could recognised the charging source of Type-C as a master,and the ID pin is high.
