Help Identify this part? 1600N729?

Hi,

Can anyone help me identify what ST component this is? It's used in an R/C transmitter I have, it's not old, built in 2019...

But I cannot figure out what ST Micro part this relates to?

I found the 'STUSB1600', but that doesnt seem to fit with the design in this circuit, and also the circuit design doesn't line up with how it's wired on this board..

Thanks so much,

• Mike

The marking looks to be a STMPE1600, but it has only QFN24 package, and it is NRND now.

N279 means it was assembled at plant N, in the year 2017 week 29.

Awesome, that lines up how it's wired in this circuit, and makes sense..

Thanks so much, this is definitely the part!
