Other Parts Discussed in Thread: TUSB4020BI, , TPS2561
TUSB4020BI two-port USB 2.0 hub on design specifications.
In the data sheet, TUSB4020BI is recommended to be designed as a self-powered USB hub,
Can I use this as a bus-powered USB hub?
Below is the time when it was possible,
To design a bus-powered circuit based on the circuit diagram of TUSB4020BPHPEVM, is the change correct as follows?
· Remove the USB power switch TPS2561 because it does not use external power from the AC adapter.
· After supplying VBUS from the host side to the regulator etc., connect it directly to the connector on the device side.
If there are errors and caveats,
I would like to have some advice.
Best regards,
