Hi R_J

You are correct, the CON3 is the internal Battery

I will look for a replacement, and see if I have any on old Laptops

Its been an uphill struggle ans Manufacturers and component suppliers really Wont or dont Help, so the folk sin this Group have really helped go in the right direction

Will Keep you updated

Stay Safe

The TP4054 is a sot23-5, just look at the datasheet, the XX4054 seems to be made by may companies with a slightly different part number

After a closer look at the picture in post #10, I see CON3 is the battery connector, so this must be the correct ic.

Aah Ok let me look

Re: BAUN - UVST - 0617,Can anybody Identify these Please?

I think this might be the Manufacturer

They are a distributer not a manufacturer. Just pick your favorite parts supplier and order one.

Noppa - Would you happen to know what SOT it is please?

I know it’s cheap, and the moment I collected it, it wasn’t worth the repair, but it’s for a friend.

I love problem solving

Thanks again..

Hey R_J I need to re-check in a few hours, so I don't give you false information.

I will attempt to draw out a basic schematic.

Here is a photo of the MicrOne version, the logo and markings are different, but I suspect the operation will be the same.

I asked if you traced out the pins to see if this is the same ic, For example, pin 3 seems to connect to CON3, is this where the battery connects???

Hi Folks - Just got back
Thanks for your responses

The component companies haven’t got a clue what it could be

This is the product

Re: BAUN - UVST - 0617,Can anybody Identify these Please?

is it related to a lithium battery?
ME4054?

Great detective work.

What do you think the component is?

Re: BAUN - UVST - 0617,Can anybody Identify these Please?

Thankyou

I have emailed a couple of component suppliers, to see if they can sell me equivalents.
I will keep you updated.

Thanks

Then is likely has to do with charging the battery, trace out the circuit as I can't tell where the traces connect to based on the picture.
There are lithium battery charge ic's like the Tp4054, this may be similar made by some odd manufacture
The TP4054 might be close, check the datasheet and see if the pins line up. It looks close from what I can see.
