ROG Ally not charging issue

A few days ago, my ROG Ally suddenly stopped charging — the charging LED wouldn’t turn on, and it wouldn’t charge at all. I took it to the official ASUS service center, and they said the motherboard needed to be replaced. However, the repair cost was too expensive, so I went to a third-party repair shop instead. They confirmed that the problem was with the PM chip, specifically the MP2845A chipset.

The issue is that we cannot find a source for the chipset data. The repair shop says the chip needs to be replaced and the proper data must be written to it in order for it to function correctly, but we have no way to obtain the necessary data.

Is there any way to get this chipset data? Please help.
