CAP1126

6 Channel Capacitive Touch Sensor with 2 LED Drivers

General Description

The CAP1126, which incorporates RightTouch

tech-

nology, is a multiple channel Capacitive Touch sensor

with multiple power LED drivers. It contains six (6) indi-

vidual capacitive touch sensor inputs with programma-

ble sensitivity for use in touch sensor applications.

Each sensor input automatically recalibrates to com-

pensate for gradual environmental changes.

The CAP1126 also contains two (2) LED drivers that

offer full-on / off, variable rate blinking, dimness con-

trols, and breathing. Each of the LED drivers may be

linked to one of the sensor inputs to be actuated when

a touch is detected. As well, each LED driver may be

individually controlled via a host controller.

The CAP1126 includes Multiple Pattern Touch recogni-

tion that allows the user to select a specific set of but-

tons to be touched simultaneously. If this pattern is

detected, then a status bit is set and an interrupt gen-

erated.

Additionally, the CAP1126 includes circuitry and sup-

port for enhanced sensor proximity detection.

The CAP1126 offers multiple power states operating at

low quiescent currents. In the Standby state of opera-

tion, one or more capacitive touch sensor inputs are

active and all LEDs may be used. If a touch is detected,

it will wake the system using the WAKE/SPI_MOSI pin.

Deep Sleep is the lowest power state available, draw-

ing 5uA (typical) of current. In this state, no sensor

inputs are active. Driving the WAKE/SPI_MOSI pin or

communications will wake the device.
