Looks pretty similar, however, SY8371B might be 3V (see attached only information I was able to find, only 11 pages).

Dear friends, I am working on Lenovo Yoga 7 14IRL8, no schematic available. Upon trouble shooting I found this chip shorted. There is a code marking S2=AB on this chip, but could not find this marking (View Photo). I thnk this chip is soldered on the 3.3V or 5v rail. Can someone help me finding the real number of the chip. Thanks in advance.

Ah, you`re right it doesn`t, thanks for pointing out the mistake. I didn`t check the typical application picture against the different package pin configurations. I`ll remove that picture.

Need help from the IC's experts

Got a Devialet Phantom reactor 2 with no power.

Was able to open this device with a lot of pain, but now I need to identify this IC.

The original IC is burned and I can only see a "|" at the beginning of the ic.

I found other IC , also 5 legs, that also starts with | but im unable to identify.

Pics attached.
Thanks for any help!
