LDS6028
PureTouch Capacitance Touch IC with
Integrated Keypad LED Drivers
The LDS6028 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
The LDS6028 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.
Featuring 15 sensor inputs, 8 of which are dual-purpose I/Os configurable as either capacitive sensor
inputs or keypad LED drivers, the LDS6028 provides the flexibility to implement multiple touch inputs
with integrated lighting effects using a single controller.
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.
On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off
threshold levels to prevent false sensor activation. The LDS6028 is offered with both SPI-compatible
and I
2C-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.
