    PSoc4 vs MBR3 proximity sensor performance

    joe.sag

      Hi there,

         

      I am working on a design where I need the best touch sensing performance available, especially to achieve long distances for proximity detection.

         

      Does the PSoC4 CapSense component have similar performance to a dedicated chip like the MBR3? Which IC would be the one to choose with the best sensitivity of all?

         

      Thanks a lot for your help.

         

      Regards,
      Joe

          Welcome in the forum, Joe.

             

          Most performance success you'll have with the antenna design for proximity switches. I think the PSoC family members do not differ too much in their sensitivity. But the MBR3 might be the best.

             

          I would suggest you to create a Support Case (top of this page -> Design Support) to get in contact with a Cypress engineer.

            Thanks a lot for your help Bob!

               

            I am currently evaluating a wire loop with 14cm (~5in) in diameter vs a PCB trace using the MBR3 evaluation kit, but am not yet too happy with the achievable range. Lets see if the support can point me into the right direction :)
