ISL29002
Light-to-Digital I
2
C Sensor
The ISL29002 is an integrated light sensor with a built-in
integrating type ADC and a standard I
2
C interface. The
device transforms illuminance, ambient light level in lux, into
a digital output signal accessible through I
2
C. The sensor
precisely converts illuminance from 1lux to 100,000lux. The
ADC features up to 15-bit effective resolution. The sensor
includes another photodiode covered with metal to reduce
the effects of dark output reading that may be significant in
low lux levels.
The ISL29002 can control display panel backlighting depending
on ambient light conditions, adding artificial intelligence by
approximating the response of a human eye. The ISL29002
can also manage portable peripheral illumination based upon
lighting conditions extending battery life.
In normal operation, the ISL29002 consumes less than 300μA
of supply current. A software power down mode is controlled
via the I
2
C interface and disables all but the I
2
C interface. The
supply current is then reduced to less than 88μA.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29002 is specified for operation over the -40°C to +85°C
ambient temperature range. It is packaged in a clear, Pb-free
8 Ld ODFN package.

NOTE: Intersil Pb-free ODFN products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both
SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
