Touch controller as standby button

[AnHi_4375051]

We think about using the touch controller “CY8CMBR3102-SX1IT” as an standby button for our product. I tested the touch button with the evaluation board and it performs very good.

Now I am wondering if the touch controller has enough immunity versus environmental factors(EMC).

Do you have practical experiences with the touch used in other projects as standby button? Are there any test results with IEC/EN 61000-4-6 (10V rms)?

best regards

Hi AnHi_4375051​,

We are checking with our product team to see if we have any test results that you have requested for.

Our MBR3 touch controllers has good immunity(EMC) and provides robust operation under extreme noise conditions.

CY8CMBR3102 device has a EMC feature that provides advanced noise immunity algorithm for superior noise immunity against external radiated and conducted noise.

Hi,

Unfortunately we do not have  test results for IEC/EN 61000-4-6 (10V rms).

But we if the design guidelines are strictly adhered to, we believe that you will be able to pass this test.

For more information please refer to the MBR3 CapSense design guide.
