Low Power Ambient Light and Proximity Sensor with Internal IR-LED and Digital Output ISL29044 The ISL29044 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED 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. For ambient light sensor ALS data conversions, an ADC converts photodiode current with a light sensitivity range up to 2000 Lux in 100ms per sample. The ADC rejects 50Hz/60Hz flicker noise caused by artificial light sources. For proximity sensor Prox data conversions, the built-in driver turns on an internal infrared LED and the proximity sensor ADC converts the reflected IR intensity to digital. This ADC rejects ambient IR noise such as sunlight and has a 547us conversion time. The ISL29044 provides low power operation of ALS and proximity sensing with a typical 133uA normal operation current 108uA for sensors and internal circuitry, ~25uA for LED with 220mA current pulses for a net 100us, repeating every 800ms or under . The ISL29044 uses both a hardware pin and software bits to indicate an interrupt event has occurred. An ALS interrupt is defined as a measurement that is outside a set window. A proximity interrupt is defined as a measurement over a threshold limit. The user may also require that both ALS/Prox interrupts occur at once, up to 16 times in a row before activating the interrupt pin. The ISL29044 is designed to operate from 2.25V to 3.63V over the -40°C to +85°C ambient temperature range. It is packaged in a clear, lead-free 8 Ld ODFN package. • Internal LED + Sensor = Complete Solution • Works under all light sources including sunlight • Dual ADCs measure ALS/Prox concurrently • <1.0uA Supply current when powered down • Temperature compensated • Pb-Free RoHS compliant Intelligent and Flexible Interrupts • Independent ALS/Prox interrupt thresholds • Adjustable interrupt persistency - 1/4/8/16 consecutive triggers required before interrupt • Display and keypad dimming adjustment and proximity sensing for - Mobile devices Smart phone, PDA, GPS - Computing devices Laptop PC, Netbook, Tablet PC - Consumer devices LCD-TV, digital picture frame, digital camera - Industrial and medical light and proximity sensing Related Literature • See AN1436, “Proximity Sensors” V_LED V_PULLUP I2C SLAVE 0 5 LED- LED+ 4 6 IRDR GND 3 7 INT SCL 2 8 SDA VDD 1 ISL29044 C1 0.1µF C3 0.1µF R1 RES1 I2C SLAVE 1 I2C SLAVE_n C2 1µF I2C-DIAGRAM I2C-DIAGRAM R2 RES1 R3 RES1 I2C MASTER SCL SDA INT CONTROLLER FIGURE TYPICAL APPLICATION FSR % 110mA GREY 20 40 220mA WHITE 110mA WHITE 220mA GREY 60 80 100 120 140 160 DISTANCE mm FIGURE PROXIMITY RESPONSE vs DISTANCE April 28, 2016 FN8305.2 CAUTION These devices are sensitive to electrostatic discharge follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 \|Copyright Intersil Americas LLC. 2012, All Rights Reserved Intersil and design is a trademark owned by Intersil Corporation or one of its subsidiaries.
