Hello,  I am trying to identify a ST Micro chip.  As far as I can tell, the markings show the following:

MHLF7A0

GH24-VG

CHN

It is used in an AFCI breaker.

Thank you!

    This is a customer part number and as such no public documentation would be available.

    How about posting a photo?

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    For whatever reason, it is not allowing me to upload a photo, but I got a better look at the text under a microscope:

    MHLF7A0

    GH2YBVG

    CHN
