Description
The TSL2572 device family provides ambient light sensing (ALS) that approximates human eye response to
light intensity under a variety of lighting conditions and through a variety of attenuation materials. Accurate ALS
measurements are the result of TAOS’ patented dual-diode technology and the UV rejection filter incorporated
in the package. In addition, the operating range is extended to 60,000 lux in sunlight when the low-gain mode
is used.
While useful for general purpose light sensing, the TSL2572 device is particularly useful for display
management to provide optimum viewing in diverse lighting conditions while extending battery life. The
TSL2572 device family is ideally suited for use in mobile handsets, TVs, tablets, monitors, and portable media
players where the display backlight may account for 50% to 70% of the system power consumption.
