LDS6020

PureTouch^™Capacitance Touch IC with Integrated

Keypad LED Drivers

The LDS6020 PureTouch™ controller empowers system designers to create streamlined, attractive and

reliable product designs with capacitive touch controls. Integrated LED drivers allow visual feedback to

be implemented when a touch occurs, without the need for host intervention.

Description

LDS6020 Features

The LDS6020 is a programmable capacitance-to-digital converter (CDC) designed for use with capacitive

sensor arrays implementing touch-based input controls including sliders, scroll wheels, and buttons.

Versatile, accurate capacitance-

to-digital converter (CDC)

•ꢀ 500ꢀkHzꢀsigma-deltaꢀCDC

Featuring 13 sensor inputs, 8 of which are dual-purpose I/Os conﬁgurable as either capacitive sensor

inputs or keypad LED drivers, the LDS6020 provides the ﬂexibility to implement multiple touch inputs

with integrated lighting effects using a single controller.

•ꢀ 13ꢀcapacitanceꢀsensorꢀinputꢀchannels

•ꢀ 2ꢀmsꢀupdateꢀrateꢀperꢀactiveꢀsensor

When conﬁgured for capacitive sensing, the I/Os are directed through an integrated switch matrix to a

500 kHz sigma-delta CDC which senses changes in the external sensor array. When a sufﬁciently large

change in capacitance occurs, a sensor activation is registered and the host processor is notiﬁed. LED

lighting effects are automatically initiated by a touch event with no processor intervention required.

•ꢀ 7.75ꢀmAꢀmaximumꢀdrivingꢀcurrentꢀ

(up to 62 mꢂ available by connecting

multiple outputs to a single LED)

On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off

threshold levels to prevent false sensor activation. The LDS6020 is offered with both SPI-compatible

and I²C-compatible interfaces (active interface selected by I/F select pin) and features a general-purpose

input/output (GPIO) and interrupt output for additional communication with the host processor.
