CAP1033

Please consider this device

The CAP1033, which incorporates RightTouch® technology, is a multiple channel capacitive touch sensor with multiple power LED drivers. It contains three (3) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor automatically recalibrates to compensate for gradual environmental changes.

The CAP1033 also contains three (3) LED drivers that offer full-on/off, variable rate blinking, dimness controls, and breathing. Each of the LED drivers may be linked to one of the sensors to be actuated when a touch is detected. As well, each LED driver may be individually controlled via a host controller.

The CAP1033 offers multiple power states operating at low quiescent currents.

During the Standby mode of operation, one or more capacitive touch sensors are active and all LEDs may be used.

The Deep Sleep mode of operation is the lowest power state available, drawing 3uA of current. During this mode, no sensors are active although all LEDs may be used. Communications will wake the device.
