Can someone help my to identify SOT-23 devices with following codes:
1. GBG - also it has a small logo on it - but I do not know whom it is.
I have another chip with same marking (and obviously functionality) but with other logo - "f".
This must be for "FAichild". But what is GBG?
2. SIs - this one looks to be Infineon(last small "s" means siemes) but I can not find SI
Online databooks does not gave any useful result.
See attached photos of both.
If you have found replacement or actual Number of Transistor with smd code "SIs" then kindly share with me, It is very important for me to know.
Awaiting for your reply ...
