三合一传感器：apds-9930 apds-9900 apds-9901
the apds-9930 provides digital ambient light sensing (als), ir led and a complete proximity detection system in a single 8 pin package. the proximityfunction offers plug and play detection to 100 mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly. the proximity detection featureoperates 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 statemachine 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 photopicresponse to light intensity in very low light condition or behind a dark faceplate.
the apds-9930 is particularly useful for display man-agement with the purpose of extending battery life and providing optimum viewing in diverselighting 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 theuser 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 efficienttransmission and reception of infrared energy which lowers overall power dissipation.
