Identify 8-SOIC with marking MZ938 (more likely 0621 or O621)

[peterpt]

I am trying to identify an ST IC with marking MZ938.  It is an 8-SOIC and it is used in a circuit which helps maintain charge on a 24V battery and is fed by a boost switching circuit.  It also has 0621 marked on it.  I assume that's the date code.

Please attach a large, clear and in-focus picture of the IC

The MZ938 is likely a production code.

I appreciate the suggestion.  I will trace it out and see if this makes sense.
