Optical Sense Backlight Reference Design with Temperature Sensing
Description
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 40V6 strings of 8 LEDs: 150mA max per stringAdjusts backlight brightness based on ambient light levelCapacitive touch slider for tuning or setting brightnessTemperature monitoring and shutdown during over-temperature conditionLowers system power and extends life of backlight and LCD
