Identify SM5212

[ThomsCircuit]

I cannot seem to locate the datasheet for SM5212. I can find MIC5212. If the two are the same then fine I'm just looking for the pinout.
This is part of a battery operated lamp with a touch sensor. Some of the traces have lifted off so I'm wanting to piece it back together as well

Trace Detail and how I believe they were routed

The MIC5212 ic is a totally different thing.

Attached datasheet of the SM5212 - it's in Chinese, so you will have to translate it if you want more than just the pinout details.

Thank you.

Looking at the pcb trace and now that I know the pin-out the VCC (4) and GND (3) make no sense. Can you help me understand how this IC works connected like this?
Board updated

Have you still got the socket that came off the pcb?

If yes, then a pic of it from the connection end and both sides of the body would help.

Your pin number labelling is way out - note it is a 6 pin connector.

The two pins you've labelled as data are actually V+ and the two pins on each outside edge are GND.

That explains a great deal. I do have a couple of these so I could try to repair it. I have a concern on how pin (4) on the 5212 is connected to VDD. I suppose the trace could be underneath the IC.
Thank you for you help with this.

Most likely.

If you've got a multimeter, just do an ohms test between pin 4 and pin 8

Learned a lot about this simple USB battery charging device. Yes VDD connects to pin 4 under the IC.
Thank you for your help with this. Very appreciated.

It's not pretty but it works now.

Touch Lamp. Value, $19.00

Wow - 'not pretty' is somewhat of an understatement
