TSC2004: Regarding long touch control on the screen

Part Number: TSC2004

Tool/software:

Hi team,

My customer is using the TSC2004, and there is an issue with long touch control on the screen where the touch is interrupted and appears to be repeatedly tapped.

We have confirmed that the waveform is generally the same as the lot that previously allowed long touch control, but we cannot identify the cause.

Could you please check the customer's circuit diagram via private message?

Best regards,

Kyohei
