Hi, berk\_2

What is the name of this device (model)?  
What function does this chip perform?  
Show the bottom of the chip?  
Take a full photo of the board.

I don’t understand exactly where it is used, but it goes to the “kynx5” gate pin on the motherboard. The board has a 5s bms and a buck converter.
