APDS-9933

Description

  The APDS-9933 provides digital ambient light sensing (ALS), IR LED and a complete proximity 
detection system in a single 8 pin package. The proximity detection feature operates well from 
bright sunlight to dark rooms. The wide dynamic range also allows for operation in short distance detection behind dark glass such as a cell phone. In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements 
providing very low average power consumption. The ALS provides a photopic response to light 
intensity in very low light condition or behind a dark faceplate.

  The APDS-9933 is particularly useful for display man-agement with the purpose of extending 
battery life and providing optimum viewing in diverse lighting conditions. Display panel and 
keyboard backlighting can account for up to 30 to 40 percent of total platform power. The ALS 
features are ideal for use in notebook PCs, LCD monitors, flat-panel televisions, and cell phones

   The proximity function is targeted specifically towards near field proximity applications. In cell phones, the proximity detection can detect when the user positions the phone close to their ear. The device is fast enough to provide proximity information at a high repetition rate needed when answering a phone call. This provides both improved “green” power saving capability and 
the added security to lock the computer when the user is not present. The addition of the micro-optics lenses within the module, provide highly efficient transmission and reception of infrared 
energy which lowers overall power dissipation.
