    cap sense low power

      Hi,

       

      We are using CY8CMBR3116-LQXIT for touch keypad interface.

       

      My question about the current consumption of chip.

       

      As you mention that "Average current consumption of 22 μA per sensor at 120-ms refresh interval" in datasheet.

       

      We did three different test to verify it.

      1. Do not configure any button or proxy sensor.

      2. Configure only one button.

      3. Configure Proxy Sensor(CS0/PS0).

      4. Proxy + 4 Button

       

      Case 1: Do not configure any button or proxy sensor.

       

       

       

       

       

       

       

      Thanks,
