Hi fellows,
I am trying to repair a Dyson DC45 battery powered hoover.
There is a trigger board in it which hosts an Attiny48 and some power stage to drive the brush motor.

Unfortunately a SO8 component burned to hell in it together with a 0603 resistor and the IC could not be identified.
The Attiny output looks to be survived the problem because when pulling the trigger it outputs high for a while and then turns off.
It is likely that it measured the current on the R10 shunt and this is why it is shut down.
I have attached a reverse engineered schematic from the part.

What type of IC could it be?
