    Temperature behaviour of PSOC4000 Capsense

    AnJu_3725101

      Hi all,

       

      I need some support about my application with a PSOC4000 Controller. I have designed a touch pad functionality for dimming a lightsource.

      I have to do some temperature tests for the device.

      At around 60°C ambient temperature the susceptibility of the sensor of the touch pad gets less sensitive. I have checked the CapSense voltage in parallel but I couldn't detect any changes of the signal.

       

      Does anyone have an explanatin for this behaviour?

       

      Kind regards

      Andreas
