    CapSense Low Power Design. Current Comsumption is enough small ?

    user_54112929

      In my design, the battery (the capacity is 50mAh) is always feed into the the pSoC4 BLE.

         

      When an user touch the device, the pSoC4 BLE should power on the system(other chips etc.). 

         

       

         

      The  pSoC 4 BLE's capsense is periodically(1sec via WDT) check the user's touch. 

         

      The Capsense Low Power Method is shown on page 64  http://www.cypress.com/?docID=50746

         

      In this low power design, What is the current consumption ? 

         

      In my case, It must be needed under 5 uA.
