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.
