description
the epl8862klwjp integrates an ambient light (als) sensor, a proximity sensor (ps) and 2d gesture sensors with built-in ir led. it isused in notebook pcs, smartphones, mids (mobile internet devices), pnds (portable navigation devices), e-books, tablet pcs, flat-panel televisions, etc. for extending battery life and for better userexperience. ambient light sensor optimizes the screen brightness to extend battery and to increase battery life. proximity sensor (ps) measures the ir reflection intensity which correlates to thedistance of the object. proximity sensor enables the device controller to turn off the lcd back-light and the touch-screen sensor when the device is held close to your ear, placed inside the pocket,purse, or bags. this function saves the battery power and avoids unintended touch-screen trigger. proximity sensor can also work as a device wake-up sensor by sensing the user waving the hand infront of the device. the 2d gesture sensor detects the waving of palm in front of the screen in 4 directions left, right, up and down. the hand gesture without the need to touch the screen adds newway of human device interaction. for example, the gesture can be used to accept a phone call in the hand-free mode while the user is driving in a car. in another example, the user wave to the screento advance or retract in the picture viewing mode without worrying the food stains from the fingers to be left on the screen.
features
 als, ps and gesture sensor with built-in ir led in a single module
 high proximity sensitivity: proximity detectable distance ranges from 0 toapproximately 10 centimeters, as set by the ir led light intensity and the programmable threshold
 minimum lux resolution: 0.001 lux/count
 large dynamic range: ambient light sensor measures 100,000 lux
 2d gesture recognition distance: 20~150 mm
 digital control and data output via i2c (100 khz and 400 khz)interface
 programmable analog gain and integration time for als and ps
60 hz compensation
 interrupt pin supports active-low microprocessor interrupt bus for ps event,programmed by the “high” and “low” thresholds
interrupt pin can also be programmed as a digital binary output pin
 ir led may be operated at current source or voltage source
 core vdd : 2.4 to 3.6 v
 active vdd pin current 320ua in als/ps mode, 450ua in gesturemode
 average current at 3.0v, based on power-saving mode.
ambient sensing mode : 30ua typical.
proximity sensing mode : 130ua typical (include ir led pulse current)
