Good day,
I have been reading this post as I am busy with a similar application.
I want a typical 13.8V charger to charge my lithium batteries with a PMID output of 5V @ 3.1A.
With battery backup I still need the 5V @ 3.1A.
The power supply / charger will supply 5V to a raspberry PI and the Pi will be damaged if the PMID output goes above 5.2V and will reset below 4.8V.
I have been testing the following example and struggling to get the above working:
So the question:
Are there any registers that I can change during production to insure that the above will work as expected or will the registers always go back to default were PMID follows the VBUS voltage?
During production the test bench will be able to handle a wider voltage than the Pi and it can be setup there.
Kind Regards,
Kallie
