MN25713E

Description
The MN25713E integrates an ambient light (ALS) sensor, a proximity sensor (PS) and with both I
2 C and
Interrupt Pin outputs and with built-in IR LED. It is used 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 user visual experience. Ambient light sensor optimizes the
screen brightness to extend battery and to increase lame life. Proximity sensor (PS) measures the IR
reflection intensity which correlates to the distance 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 in front of the device.
