YX86 1108 Device Identification

Hello Forum,

I am trying to fix a solar power light (water got inside and the circuit has been badly damaged). I am trying to find out what the 8 pin DIL, labelled YX86 1108 is?

I have attached a picture. However, I don't know if the quality is any good.

Thank you in advance,
Harold Clements

If I was going to try to fix this I would:

1) note the position and orientation of each part
2) remove each part
3) clean/repair the board
4) get a new switch
5) clean up the components
6) re-insert and solder the components
7) test.

If it didn't work, I'd take step 8

8) buy a new one.

Given the time and effort to do all of these things, you may find a way to skip 7 of these steps.

Hello Steve, thank you for your reply.

I was more trying to find out what the YX86 1108 device is. It looks quite a simple, single layer board that I just going to make a new one will all new components.

Kind Regards,
Harold Clements

That would be the $64,000 question.

It could be a common part rebadged with some internal "secret" marking, or it could be a completely custom part.

I also notes what appears to be a TO-92 device with a lead missing. Do you know what that is?

You may have some success by reverse engineering a schematic. It is possible that you might recognise the device as (say) a 555 or a 741. However it won't be something quite that easy since neither of these will work with such a low supply rail. Perhaps it's an LM3909 But that won't charge the battery.

The easiest solution may be (8) above -- even if you have to rip the guts out of a similar unit to repair this one.

Just to follow up (incase anyone is interested). Whilst attempting to clean the PCB, the legs on one side of the device had completely corroded. This allowed me to lever up the device and the see the silk screen. This revelled the the part number that I am looking is in fact an YX861. Google has told me that an YX861 is an "Supply YX861 Solar LED Christmas lights controller" (http://www.hqew.com/buyer/ec_detail15425406.html). My next problem is trying to source one that won't be more expensive than buying the whole unit.

Hi Harold!
Did you manage to find this component? I am looking for the same. I am also repair a mini kit of solar lights (same as Christmas lights, but only while color).
Thank you for your answer!

Hi Haroldjclements. YX861-1108 is a solar-driver IC
manufactured by YX electronics in Shenzen, China.
I presume you have the "rope-light" design (without 411 SCR).
Slider-switch SW1 grounds/breaks pin5 in B or C position, while B1[+] is disconnected in "off" position.

A solar garden light is very inexpensive. If you buy a new one then seal around the solar panel so the electronics inside does not get wet. The bottom should be open a little so that humidity and condensation can get out.

A modern solar garden light comes with a Ni-MH battery cell in a stainless steel case that does not rust away like the old Ni-Cad cells. Its solar panel has a glass cover not like the old plastic covered ones that got sunburned.
