I would suggest to put capacitors to ground very close to IC pins and IC ground. Then i would ask to do the test and if issue gets resolved then removing capacitors one by one till we have the minimum needed.
For example: A single 1u cap on the 3 pins…
Hi Sanjay,
I will send you the circuit of touch-panel and the measurement enviroment.

Part Number: TSC2017 Hi all,
I would like to know the results of IEC61400-4-2.
Which of a) to c) does it apply?
a) The device works normally when the voltage of the target is applied.
b) The device malfunctions, but it does not stop working.
c) Operator…
Part Number: TSC2017 When Vdd = 0V, the voltage range that can be input to the C1 (SDA) and D1 (SCL) pins is -0.3V to Vdd+0.3V, or ±0.3V, is this correct? If I were to pull up with an external 3.3V, would the semiconductors be damaged?
