That is way too advanced for me!!It's either that or add caps and/or move the PFET out of the TPL5110 board.
The last option might give the most stable result. A 3-pin sot23 adapter can be used, and I have soldered one before on the copper side of a doughnut board for quick testing. One board or power domain for load switching, one for low power TPL5110. Add some caps for the PFET board too.
I've gone the 3 x 10R route, and IT WORKS! It is running for half a day now, and I have also tested a full reset (unplug completely) a few times. I have now connected it to its final destination (the solar panel controller) and that works too! I don't think I could have pulled this off without your help, so a big thank you again!
The bad news: I have to build a second one. Let's see what this brings up
