Does anybody know which IC this is? I cannot find anything for "2746 QA7A" or any combination of it. Neither do I recognise the manufacturer. The IC is actually very small, so I cannot take a better photo of it.
What I already found out: The IC is connected to six touch keys, the upper five pins and the first pin on the lower left are connected to the touch pads. Then there are 3 data lines connected to an ST32. May be I2C.
Thanks for any hint!
