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 2 C
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 ALS pin
provides an analog output current proportional to the
measured light (420 μ A 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 540 μ s
conversion time.
The ISL29030A provides low-power operation of the ALS and
proximity sensing, with a typical 138 μ A normal operation current
(110 μ A for sensors and internal circuitry; ~28 μ A for external LED,
with 220mA current pulses for a net 100 μ s, 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.
