Description

The TSL4531 family of devices provides ambient light sensing (ALS) that approximates human eye response

under a variety of lighting conditions. The devices have three selectable integration times and provide a direct

16-bit lux output via an I C bus interface. The wide dynamic range of the ALS makes it particularly useful in

outdoor applications where it is exposed to direct sunlight. The device is ideal for use in automatic control of

street lights and security, billboard, and automotive lighting. The TSL4531 devices can also be used in solid state

and general lighting for automatic control and daylight harvesting to maximize energy conservation. Other

applications include display backlight control to extend battery life and optimize visibility in cell phones, tablets,

and notebooks.
