CAP1214

Multiple Channel Capacitive Touch

Sensor and LED Driver

Datasheet

PRODUCT FEATURES

General Description

Features

Fourteen (14) capacitive touch sensor inputs

The CAP1214 is a multiple channel Capacitive Touch

sensor and LED Driver.¹

—

Compensates for variable sensing pads

Programmable sensitivity

High SNR allows for easy tuning

Automatic recalibration

Slider acceleration and position detection

Proximity detection

The CAP1214 contains up to fourteen (14) individual

Capacitive Touch sensor inputs with programmable

sensitivity for use in touch button and slider switch

applications. Each sensor input contains automatic

recalibration with programmable time delays.

Lid closure detection

Low power operation

The CAP1214 includes compensation circuitry that

provides uniform touch sensitivity across a wide range

of external sensing pad capacitance.

—

4.5uA quiescent current in Deep Sleep

—

250uA quiescent current in Sleep, monitoring 1 button

FEEDBACK pin can drive a piezo transducer when a

touch is detected

User controlled reset

Low external component count

SMBus 2.0 compliant interface to change operating

parameters to work in a wide variety of systems

The CAP1214 also contains eleven (11) low side LED

drivers that offer full-on / off, variable rate blinking,

dimness controls, and breathing. LED outputs can be

linked to capacitive sensor channels.

Applications

—

Block Read and Write function for quick tasking

Consumer Electronics

Desktop and Notebook PCs

LCD Monitors

Eleven (11) LED driver outputs

—

Programmable blink, breathe, and dimness controls

8 configurable as GPIOs

LEDs can be linked to capacitive sensor channels

Development boards and software available

Available in 32-pin 5mm x 5mm QFN Lead-free

RoHS Compliant package
