Need help IDing a component
(1/1)
GadgetBoy:
Can someone help me identify and/or find a datasheet for this chip?
Mr.B:
It is very likely that you will never find a datasheet.
Unknown LED driver from Aliexpress = undocumented.
Even if there was a datasheet, the chances of it being in English are almost zero.
mbless:
It appears to be touchpad IC ttp223-ba6. Don't know if that fits its role on the PCB given we only LEDs.

And seriously, a picture of a monitor  :palm:

That's actually a great help (and yes, I used a picture I took of the monitor because it was handy. Playing around with a USB microscope, I wanted to quickly send a photo of it to a friend. The picture was perfectly applicable for the question).

I *SHOULD* have mentioned that it's one of those cute little usb LED boards that have a touch pad on the back to turn it on and off.
