      ISL29029IROZ-T7
      Low Power Ambient Light and Proximity Sensor with Intelligent Interrupt and Sleep ModesThe ISL29029 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel. The flexible interrupt scheme is designed for minimal microcontroller utilization.Features• Works Under All Light Sources Including Sunlight• Dual ADCs Measure ALS/Prox Concurrently• Intelligent Interrupt Scheme Simplifies μC Code• 0.5% Typical NonlinearityAmbient Light Sensing• Simple Output Code Directly Proportional to lux• 50Hz/60Hz Flicker Noise and IR Rejection• Light Sensor Close to Human Eye Response• Selectable 125/2000 Lux RangeProximity Sensing• Proximity Sensor with Broad IR Spectrum- Can Use 850nm and 950nm External IR LEDs• IR LED Driver with I2C Programmable Sink Currents- Net 100μs Pulse with 110mA or 220mA Amplitudes- Periodic Sleep Time up to 800ms Between Pulses• Ambient IR Noise Cancellation (Including Sunlight)Intelligent and Flexible Interrupts• Independent ALS/PROX Interrupt Thresholds• Adjustable Interrupt Persistency- 1/4/8/16 Consecutive Triggers Required Before InterruptUltra Low Power• 138μA DC Typical Supply Current for ALS/Prox Sensing- 110μA for Sensors and Internal Circuitry- 28μA Typical Current for External IR LED (Assuming 220mAfor 100μs Every 800ms)• <1.0μA Supply Current When Powered DownEasy to Use• Set Registers; Wait for Interrupt• I2C (SMBus Compatible) Output• Temperature Compensated• Tiny ODFN8 2.0x2.1x0.7 (mm) PackageAdditional Features• 1.7V to 3.63V Supply for I2C Interface• 2.25V to 3.63V Sensor Power Supply• Pb-Free (RoHS compliant)• I2C Address Selection PinApplications• Display and Keypad Dimming Adjustment and Proximity Sensing for:- Mobile Devices: Smart Phone, PDA, GPS- Computing Devices: Laptop PC, Netbook- Consumer Devices: LCD-TV, Digital Picture Frame, Digital Camera• Industrial and Medical Light and Proximity Sensing
