Something like an e-file number, such as E354278 for STMPS2151. I can't find the component on the UL pages.

Please update information about STMPS2151 on https://www.st.com/en/switches-and-multiplexers/stmps2151.html#documentation

This is "AN2148 STOTG04 IN AUDIO CARKIT ENVIRONMENT" But inside pdf there is

Also there is no "STMPS2151" text inside AN2148. May be this application note isn't about STMPS2151?

ALso I suggest add typical schematic on DS5410 Enhanced single channel power switches For example I don't know should I use capasitor on In and OUT pins?

No, there are currently no plans to carry out UL certification for the STMPS2252 as well.

With a corresponding project size, this can be taken into account, please contact your preferred distributor.

What does this mean in numbers "corresponding project size"?

[Peter BENSCH]

Well, it has to be taken into account that such certification cannot be obtained free of charge from UL. For this reason, it is recommended that you explain the need for such certification in a direct discussion with us or through your distributor.

We need this chip as a replacement for the TI variant TPS2052BDGN. This component is UL-recognized and we use the component in our devices, which themselves have UL approval. If components have to be replaced in such devices, a declaration to UL regarding a change is easier if this replacement is already listed with UL. If that is not possible, then we have to find another replacement.

Best regards,
