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.

Features
• Internal LED + Sensor = Complete Solution
• Works under all light sources including sunlight
• Dual ADCs measure ALS/Prox concurrently
• <1.0μA 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

Applications
• 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
