SX8661

Low Power, Capacitive Button Touch and Proximity Controller

(8 sensors) with LED Drivers and Analog Output

Figure 7

Quickstart LED and AOI reporting

Figure 7 shows the reporting on the LEDs and the AOI for the quickstart application.

The LEDs operate in triple reporting mode. In triple reporting mode the LEDs have three light intensities.

- OFF: out of proximity, no touch,

- Proximity: proximity detected,

- ON: button touched.

In case no fingers/hand is detected (out of proximity) all LEDs will be OFF and the AOI indicates the idle level.

In case a finger/hand is approaching proximity is detected and all LEDs will light up to 50% of the maximum

intensity. The AOI goes to the proximity voltage level (in the quickstart application the proximity level is chosen

identical to the idle level).

In case a button is touched the corresponding LED will go to 100% of intensity and the AOI voltage level indicates

the button that is touched.
