problem trying to identify and find the correct chip specifications for a few of the chips.
One of them (U504) can be seen in the photograph and schematic below.
EDIT: This chip have probably been resolved to be the MAX8922L as shown in post #6.
So the next chip we would like to resolve is the U303 shown in post #9.
U303 has been resolved as shown in post #13.
We need this info in order to complete the "The all-in-one Galaxy S2 Hack Pack" in the
add-on post "The GT-I9100 Hack Pack AddOn-1". (For further details see that thread.)
As is shown in that link, it is listed by its Samsung part-number as:
"SS6000GQW / IC-POWER SUPERVISOR". But that chip is nowhere to be found on internet,
so it must be something else, or at least very similar to something else.
The other chips we need info about, are:
U101 Duplexer/Antenna Switch Module
U303 Samsung:1203-006847 ? ? "AA1 114" / "IC-POWER SUPERVISOR" U504 Samsung:1203-006884 ? ? "SS6000GQW / IC-POWER SUPERVISOR"F100 Samsung:2910-000125 ? ? "DUPLEXER-SAW"
