Description
provides digital ambient light
sensing (ALS), IR LED and a complete proximity
detection system in a single 8 pin package. The
proximity function offers plug and play detection to
100mm (without front glass) thus eliminating the need
for factory calibration of the end equipment or sub-
assembly. 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-9900/9901 is particularly useful for display
management 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.
