Magic Pie 5 internal controller scorched 10 pin SMD IC bottom side of 1 pcb

[Miward]

Hi

As in a topic I'm looking for symbol or numbers from IC SMD 10 pin which in mounted on bottom side of first accessible PCB (not the one with mosfets). Unfortunately cannot read numbers of it as it is scorched and Pie 5 it is dead. chip is located close to main black and red battery incoming terminals. There are some numbers poorly visible but first line last two digits looks like 92 second line looks like 5B?3  or something close ? - unreadable. I did tried to google part but with no luck. Any help is appreciated. maybe one of you has old faulty controller and can read the numbers.


thanks

Mike
