Hi,
I designed the PCB where used STUSB4500. I encountered a problem: when I plug USB Type-C connector, USB PD adapter disconnects from my PCB. Could you advise what may reason to disconnect USB PD adapter?
Power profiles, which I tried is: 20V 1A (PDO3 default) and 20V 3.25 (also PDO3 manually configured on STUSB4500, this profile appropriate to maximum power of my USB PD adapter 65W 20V 3.25A)
This problem exists for USB PD adapters from differences vendors
Peak current, which I detected when BQ25713 trying to start charging is less than 3A
When I supplied battery manager from DC power supplier (bypass STUSB4500), battery normal charging
What I see on VBUS, when plug USB Type-C connector
When STUSB4500 block disconnect from load (all other terms not change) on it output I can see stable 20V
