Hi Brendan,
Thank you for getting back to me on this. There is a high chance that my understanding of the power path setup is just good enough or that I’ve misunderstood the functionality. So let me try to explain better.
Looking at the application layoyut for the MP2759, what we want to achive is to create a setup where our standard port/connector for the battery is an USB-C port, so that different types of powerbanks can be connected. This is fairly simple and this should be possible. But the questions goes mainly towards Scenario 3 from above. If we have a USB-C connector, meant for connecting powerbanks, can we then also use the same connector to connect a standard power source (like a 5V wall plug connector). I’ve tried to picture it here, use the application layout for the MP2759:
So basically the battery pack can be an USB power source of any kind and not always a battery. How will the IC handle this?
Also, you mention a 2 stage solution for higher voltage. Can you elaborate a bit on this?
Thanks in advance.
