Component without datasheet IC's labeled "IN1S313I" and"IN1S424I"

Hello
I am troubleshooting a couple of coolmaster ATX power supplies.
I suspected that the faulty components are the sps supervisor IC's labeled "IN1S313I" and"IN1S424I".
I couldn't find any information about them online exept for their name, role and the manufacturer witch is "infsitronix".
No datasheet, no pinout, i even tried to email infsitronix but no reply so far.
I can't find a supplier to buy it either.
Any help of how to test it and where to buy/order it is appreciated.

Regards.

IN1S313I-sag = WT7510A = EST7610A and presumably = PS113A

Thank lotas,this is very helpful since the Weltrend ic's can be purchased while Infsitronix company don't have distributors (that i know of) and didn't reply to my email.
What about the IN1S424I?
I hope these pictures help

I can’t say anything about IN1S424I, probably some kind of relabeling of another chip.
