The ISL29044A 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 micro-controller 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
