NOA3315

NOA3315 Digital Proximity Sensor with Dual Ambient Light Sensors and Interrupt Description The NOA3315 combines an advanced digital proximity sensor and LED driver with dual ambient light sensors (ALS) and tri−mode I2C interface with interrupt capability in an integrated monolithic device. Multiple power management features and very low active sensing power consumption directly address the power requirements of battery operated mobile phones and mobile internet devices. The proximity sensor measures reflected light intensity with a high degree of precision and excellent ambient light rejection. The NOA3315 enables a proximity sensor system with a 16:1 programmable LED drive current range and a 30 dB overall proximity detection range. The dual ambient light sensors include one with a photopic light filter and one with no filter. Both have dark current compensation and high sensitivity eliminating inaccurate light level detection and insuring proper backlight control even in the presence of dark cover glass. The NOA3315 is ideal for improving the user experience by enhancing the screen interface with the ability to measure distance for near/far detection in real time and the ability to respond to ambient lighting conditions to control display backlight intensity. www.onsemi.com CUDFN8 CU SUFFIX 1 CASE 505AP PIN CONNECTIONS VDD 1 8 SCL VSS 2 7 SDA LED_GND 3 6 NC LED 4 5 INT (Top View) ORDERING INFORMATION Device Package Shipping NOA3315CUTAG* CUDFN8 (Pb−Free) ...
