Hello @abdelb88,

Welcome to the community!

Unfortunately, I was unable to locate this part. Maybe someone else in the community knows what the part is.

Your part marking format and footprint match patterns similar to

[AOZ13984DI-02](https://www.digikey.com/en/products/detail/alpha-omega-semiconductor-inc/AOZ13984DI-02/13682301)  
and

Relatively certain your part is manufactured by [Alpha and Omega Semi](https://www.digikey.com/en/supplier-centers/alpha-and-omega-semiconductor)

I haven’t been able to find a matching BL part number code from them. It might be for a specific manufacturer.
