Low Power Ambient Light and Proximity Sensor with

Intelligent Interrupt and Sleep Modes

ISL29029

The ISL29029 is an integrated ambient and infrared light-to-digital

converter with a built-in IR LED driver and I

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 external 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 540μs conversion

time.

The ISL29029 provides low power operation of ALS and PROX

sensing with a typical 138μA normal operation current (110μA for

sensors and internal circuitry, ~28μA for external LED) with 220mA

current pulses for a net 100μs, repeating every 800ms (or under).

The ISL29029 uses both a hardware pin and software bits to

indicate an interrupt event has occurred. An ALS or PROX

interrupt is defined as a measurement which is outside a set

window. 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 ISL29029 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 lead ODFN package.
