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 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 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 540 μ s conversion
time.
The ISL29029 provides low power operation of ALS and PROX
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 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.
