Trying to identify a couple of tiny ICs
I started by 1st 2 digit codes and found too many, then searched by package type and found these to be unregistered but used by Fairchild/ON Semi.

This is not the same chip, but getting close.

I can't tell by photo without dimensions but looks like a BGA package called 4-WLCSP (0.80x0.80)

Good luck - at least I reduced the millions of possibilities to a few thousand
