Low Power Ambient Light and Proximity Sensor with Intelligent Interrupt and
Sleep Modes - Analog and Digital Out
FN7722
Rev 2.00
November 12, 2012
The ISL29030A is an integrated ambient and infrared
light-to-digital converter with a built-in IR LED driver 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 of
2000 lux) in 100ms per sample. The ADC rejects 50Hz/60Hz
flicker noise caused by artificial light sources. The IALS pin
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.
