ISL29002

The ISL29002 is an integrated light sensor with a built-in

device transforms illuminance, ambient light level in lux, into

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

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.
