Identify SM5212

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


component detail
 
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.

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?

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.

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.
