Fairchild Semiconductor Expands Support for Mobile Device Designs with Ambient Light and Proximity Sensors

To address these complex needs, Fairchild Semiconductor has introduced a series of ambient light sensors (ALS) and proximity sensors (PS). Ambient light sensors allow real-time brightness control in response to ambient lighting, while proximity sensors can be used to turn backlighting on and off based on user interactions, usage models and power conservation requirements.

The FLD000xx family consists of digital ALS devices, including the FLD00042 offering pure ALS functionality; the FLD00050 ALS with PS in 2-in-1, adding the proximity sensing function as well as a driver for external IRLEDs; and the FLD00060 ALS with PS in 3-in-1 where the IRLED is included.

With the introduction of the ALS and PS devices, Fairchild is able to offer one of the largest portfolios of ambient light solutions on the market. The broad solution and capabilities offerings coupled with a reliable supply chain process is what makes Fairchild set to provide designers with exactly what they need to optimize their systems. These devices provide the functionality needed with relatively simple circuit design by requiring minimal optoelectronics knowledge.
