Low Power Ambient Light and Proximity Sensor with

Intelligent Interrupt and Sleep Modes - Analog and

Digital Out

ISL29030A

The ISL29030A is an integrated ambient and infrared

light-to-digital converter with a built-in IR LED driver and I

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 of

2000 lux) in 100ms per sample. The ADC rejects 50Hz/60Hz

flicker noise caused by artificial light sources. The I

provides an analog output current proportional to the

measured light (420μA FSR).

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 ISL29030A provides low-power operation of the ALS and

proximity 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 ISL29030A 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 can configure the device so that ALS

and proximity interrupts occur simultaneously, up to 16 times

in a row, before the interrupt pin is activated.

The ISL29030A is designed to operate at 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.
