NOA3301

NOA3301 Digital Proximity Sensor with Ambient Light Sensor and Interrupt Description The NOA3301 combines an advanced digital proximity sensor and LED driver with an ambient light sensor (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 NOA3301 enables a proximity sensor system with a 32:1 programmable LED drive current range and a 30 dB overall proximity detection threshold range. The photopic light response, dark current compensation and high sensitivity of the ambient light sensor eliminates inaccurate light level detection, insuring proper backlight control even in the presence of dark cover glass. The NOA3301 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.
