There is another strange thing with this LV8013... it has charge pump, output from it is ~13V, but motor is definitely powered from battery (via _-MOSFET that I had to replace earlier as faulty). At this moment, I am not sure where this voltage is used, and I can't imagine someone just blindly followed the data sheet and left all recommended components on bard, only to use only a fraction of the the functionality of the IC.

Just a guess could the 13V be for the flash?

Business-like approach was simply not encoded in my DNA, that's it.

This is great stuff and worthy of a book mark.
