May 1, 2017 at 7:55 comment added Nicolo Castro Thanks to the suggestion by Ali Chan I realised that I actually have 6V coming in from the batteries, and the power multiplexors like the one you suggested all have a operating voltage up to 5.5V, so I'm not sure they would work in my case.

When there's an IC built specifically for the job you need, it's easier to use that and be sure it'll work well in the future than it is to use your own system that you're uncertain of. This also gives you the ability to limit current, and to manually switch the power source as well--you can switch to use the battery even if the power supply is plugged in, using the appropriate signals to D0 and D1.
