Hi, you might also want to look over the following topics which might be food for thought. related
It’s actually quite rare for this MAX PMIC to actually fail electrically, In almost all instances of failure that I’ve seen for this IC they have been almost always exclusively physical damage (chips/cracks etc) or detached balls/pads.
Even in cases of liquid damage they’re quite durable and usually function normally after removing, cleaning and reballing. (only if you have experience reballing)
If you spotted liquid/corrosion around or under the IC then it might be worth giving it a flux boil first if your measurements don’t read normally on the surrounding components.
