Here it is in Chinese only http://hmsemi.com/downfile/HM4052.PDF It looks like it may be replaceable by other ICs, but I see no direct replacement.
It is really my fault. I tried to diagnose it and it died while I was trying to measure battery current, and I think my contact was not very reliable, so the battery "connected" and "disconnected" very rapidly. Of course I could lie, but I don't want to do that.

no its not your fault! you opened it up and diagnosed it is the effect of the cause that it wont get charged. this is typical china products. its lucky if we can fix it, but why we should be blamed of its unreliability? f*ck it, if its me, i close it up i'll make a report to seller, whether i did or didnt open it up, either way i'll file a complaint anyway. anyway, maybe you can find pin compatible battery charging IC in digikey? if you insist to "not lie" or want to keep it in its "crippled" form, like the one china product i have here.

That's what I'm trying to do. I don't even care about it being pin-compatible, there is plenty of space for bodging there. There are some very similar ICs, I just need to find something in bigger packages.
It is not the highest quality product, for sure. But I also don't wan to deal with returns and all that stuff.

yes this is another major factor why we prefer to fix it to death on our own. sometime its better the hassle than to pay 10X of the big boy brand (but maybe its just me). good luck.

I mean, it is also not my only scope, it is essentially a toy for me, so it turning into a repair project is not a big deal.
