STUSB4500 Variable Voltage

mreilly · ‎2025-06-13

Hello,

Is there a way to set up the Sink PDO to take in a variable voltage?

I would like to set up
PDO2 5-20V 3Amps

PDO3 5-20V 5Amps

My plan is to use the Power Ok GPIOs to determine how much current I have and do some down stream current limiting.

Thanks

Dear mreilly,

Sorry for the late answer, I missed your question.

No, it is not possible to program a variable voltage inside the STUSB4500.
