I have the following situation:I have a custom PCB with a 4 port HUB ic on it (TUSB8041IRGCR). The UFP of the hub is connected to my phone and there are 4 DFP.My phone negotiates with the PD controller via CC lines about what voltage it wants when p...

How do i set the STUSB4700 so that it sources 12V 3A with the help of the GPIO pins (NO SOFTWARE)I read in the datasheet that there are several standard PDO configurations, selectable via GPIOs. But how? How do I say that i just want the PD controlle...

Thank you.I cannot find any information in the datasheet about this: Configure GPIOs: Pull GPIO0 to GND and GPIO1 and GPIO2 to 5V to set the STUSB4700 for 12V 3A output.Can you give a reference?

I forgot to mention:I have a device (DFP) which connects to the UFP port of the hub IC on my PCB, but this device sinks power (12V negotiated). So my CC lines connect to the PD controller where it will be indicated as DFP (?). Will this also affect t...

Thank you for your reaction :)To be sure, I do not need to do any other configurations but just Pull GPIO0 to GND and GPIO1 and GPIO2 pulled up to 5V (?) But where does STUSB4700 get its 12V from then? What is then the connection between the STUSB4...

I have a PD Powerbank which can handle alot of PDO'sHow would i connect this to the STUSB4700 for a 12V 3A factory configuration (since i dont have the option for software programming)How would i do this?
