See picture above for exact markings. No markings on the bottom of the IC.Battery powered device (low voltage)Markings:ST (e3) 7B589VA1814PHL 423Alternate version has similar markings. Maybe just a date code change?ST (e3) 7B474VA1814PHL 423
So, you're saying that the markings I'm seeing, while not published, match some internal documentation that gives you confidence that these are actually TSZ124IPT parts?
@Peter BENSCH Why does this chip have that marking? I don't see any reference to that marking in the datasheet you linked. Is it maybe an older marking?I would love to see @Community member's suggestion implemented.
