6 Channel Capacitive Touch

Sensor with 2 LED Drivers

Datasheet

PRODUCT FEATURES

General Description

Applications

Desktop and Notebook PC’s

LCD Monitors

Printers

The CAP1026 is a multiple channel Capacitive Touch

sensor with multiple power LED drivers. It contains six

(6) individual Capacitive Touch sensor inputs with

programmable sensitivity for use in touch sensor

applications. Each sensor automatically recalibrates to

compensate for gradual environmental changes.

Features

Six (6) Capacitive Touch Sensor Inputs

The CAP1026 also contains two (2) 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.

—

Programmable sensitivity

Automatic recalibration

Individual thresholds for each button

Flexible Capacitive Touch Sense algorithm

Multiple Communication interfaces

—

SMBus / I²C compliant interface

SMSC BC-Link interface

SPI communications

Pin selectable communications protocol and multiple

slave addresses (SMBus / I²C only)

The CAP1026 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. If a touch is detected, then it will wake the

system using the WAKE/SPI_MOSI pin.

Low Power operation

—

3uA quiescent current in Deep Sleep

Samples one or more channels in Standby

Two (2) LED Driver Outputs

—

Open Drain or Push-Pull

Programmable blink, breathe, and dimness controls

Can be linked to Capacitive Touch Sensors

The Deep Sleep mode of operation is the lowest power

state available drawing 3uA of current. During this

mode, no sensors are activethough all LEDs may be

used. Driving the WAKE/SPI_MOSI pin or

communications will wake the device.

Dedicated Wake output flags touches in low power
