Optical Sense Backlight Reference Design with Temperature Sensing
TIDA-01008
Overview
This reference design conserves power and extends life of LCD and backlight by adjusting the backlight brightness relative to the ambient light level. The capTIvate touch slider allows the brightness to be finetuned per the user's brightness preference. The sensitive thermal requirements of the LCD display is monitored by the remote temperature sensors enabling thermal shutdown to protect the system.
Features
- Operating range from 4V to 40V
- 6 strings of 8 LEDs, 150mA max per string
- Adjusts backlight brightness based on ambient light level
- Capacitive touch slider for tuning or setting brightness
- Temperature monitoring and shutdown during over-temperature condition
- Lowers system power and extends life of backlight and LCD
