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.
