ISL29028IROZ规格书详情
The ISL29028 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 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 540μs conversion time.
The ISL29028 provides low power operation of 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 ISL29028 uses both a hardware pin and software
bits to indicate an interrupt event has occurred. An ALS
interrupt is defined as a measurement which 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 ISL29028 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.
