DESCRIPTION
The LDS6100 Family of capacitive touch controllers
enables streamlining of the human-machine interface
through the implementation of touch-based user
inputs such as touch buttons, sliders, and scroll
wheels. Employing a finely tuned sigma-delta
capacitance-to-digital converter and proprietary
noise-filtering algorithms, each device is able to
reliably sense small changes in capacitance, allowing
touch-based inputs to replace a side variety of
mechanical input types. On-chip automatic
calibration accounts for environmental changes such
as temperature, humidity, and dust and is executed
automatically.
The LDS6100 Family consists of eight products, four
(LDS6100/4/7/8) focusing exclusively on touch
functionality, with another four (LDS6120/4/6/8)
include LED drivers for integrated visual feedback
when a touch occurs. Up to 20 capacitive sensor
input pins may be supported, approximately half of
which may be optionally configured as output status
pins in Direct Communication Mode (DCM) which
allows emulation of mechanical buttons for more
seamless integration. On the four LDS6120
offerings, the other half of the sensors not
configurable as DCM outputs may be optionally
configured as LED drivers, enabling integrated visual
feedback for touch applications.
The LDS6100 Family supports a touch sensor supply
voltages from 1.65 to 5.5V. All support SPI, I2C, and
SMBus-compatible serial interfaces and offer both a
General Purpose I/O (GPIO) and VDDIO support,
enabling 1.65V to 5.5V voltage interface support.
Typical touch sensor operating power for the device
is less than 125uW***. and a LED driver supply
voltage from 3.0V to 5.5V. Package offerings include
thin form factor (0.8mm max, 0.75mm nominal) 4mm
x 4mm 28-pin and 5mm x 5mm 40-pin TQFN
packages and a 10.2mm x 5.3mm 28-pin SSOP
package.
