Discussion - Hardware / FT601 VBUS pin
« on: September 19, 2022, 08:31:00 AM »
Hi,
i am drawing PCB with FT601 and i am confused about VBUS pin.
In datasheet
https://ftdichip.com/wp-content/uploads/2020/07/DS_FT600Q-FT601Q-IC-Datasheet.pdf
at Figure 6.1, 6.2, 6.3, 7.1 and 7.2 is VBUS connected directly to USB +5V.

In UMFT60xx module schematic
https://ftdichip.com/wp-content/uploads/2020/07/DS_UMFT60xx-module-datasheet.pdf
is VBUS pin connected to USB +5V through 4k7+10k divider.

What is the right way to connect VBUS pin ? And what is purpose of that pin (datasheet only claims "USB BUS power input") ?

Thanks,
Michal
