Why charging MOSFET overheating?
Why do charging MOSFET do overheating when there is a short circuit on PP_VCC_MAIN?
Is this a good question?

Because it’s the “thinnest wire” on that line. So even though it’s not the component that is shorting the line, that mosfet is still on VCC main and it’s a very “thin” wire. A lot of current going through a very small wire is liable to generate heat. It’s the same in a failed capacitor, because a failed cap is also generally a very ‘thin” wire where a lot of current is rushing through to ground.
