The ISL29043 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
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 internal 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 ISL29043 provides low power operation of ALS and
proximity sensing with a typical 136μA normal operation
current (110μA for sensors and internal circuitry, ~28μA for
LED) with 220mA current pulses for a net 100μs, repeating
every 800ms (or under).
The ISL29043 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 may also require that both ALS/Prox
interrupts occur at once, up to 16 times in a row before
activating the interrupt pin.
The ISL29043 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 10 Ld ODFN package.
