NOA2301W

NOA2301W Digital Proximity Sensor with Interrupt Description The NOA2301W combines an advanced digital proximity sensor and LED driver coupled with a 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 NOA2301W enables a proximity sensor system with a 16:1 programmable LED drive current range and a 30 dB overall proximity detection range. The NOA2301W 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. www.onsemi.com AMBIENT LIGHT PROXIMITY SENSOR Features Proximity Sensor and LED Driver in One Device ORDERING INFORMATION Proximity Detection Distance Threshold I2C Programmable with Device Wafer Size Temp Range 12−bit Resolution and Eight Integration Time Ranges (16−bit effective resolution) NOA2301W 200 mm wafer −40°C to 80°C Effective for Measuring Distances up to 200 mm and Beyond Excellent IR and Ambient Light Rejection including Sunlight (up to 50K lux) and CFL Interference Programmable LED Drive Current from 10 mA to 160 mA in 5 mA Steps, No External Resistor Required User Programmable LED Pulse Frequenc...
