Integrated keypad LED drivers
The LDS6028 features integrated keypad LED drivers enabling the implementation of visual feedback for
touch-based controls and fun lighting effects. The keypad LEDs may be powered either from Vbattery
directly or from a regulated voltage supply. On/off transition times are programmed globally for all LEDs
and maximum current may be programmed for each LED individually. LEDs may be either manually
controlled or synchronized to automatically trigger when a touch event occurs.
Ideal solution for portable applications
The LDS6028 is optimized for minimal power consumption, with touch sensor circuits operating from
a 1.8V supply voltage. In full power mode, sensor conversion and calibration occur continuously,
minimizing the time between touch event and touch detection. With its ultra-low touch sensor power
consumption of <150 uW (typical), the LDS6028 may be operated continuously in full power mode,
eliminating the need for introduced latencies that can cause noticeable delays and degrade the
user experience.
The total solution footprint is also optimized for portable applications, with the functionality of multiple
components consolidated into a single device. With integrated keypad LED driver functionality, the
LDS6028 is a flexible solution combining the functionality of two discrete ICs into a compact 5mm x 5mm
TQFNpackagewith0.75mmpackagethickness.
