Small, Low Power, Current-Output
Ambient Light Photo Detect IC
The ISL29006, ISL29007, and ISL29008 are light-to-current
silicon optical sensors combining a photodiode array and a
current amplifier on a single monolithic IC. The photodiode’s
spectral sensitivity approximates the human eye response
peaking at 550nm with virtually no infrared (IR) response.
Exposed to light, these light sensors give current outputs
that are linearly proportional to the light intensity. The output
of ISL29006 is configured as a current source, and the
output of ISL29007 is configured as a current sink. Both
ISL29006 and ISL29007 offer an EN pin that can be used for
a polling scheme to extend the battery life of portable
devices.
The ISL29008 has dual outputs simultaneously sinking and
sourcing current. With output currents at opposite polarity, it
can simultaneously control two light sources/drivers that
have incongruent illumination requirement depending on
ambient light conditions. For example, at bright ambient light
levels, display backpanels need more intensity while the
keyboard illumination needs to be dimmer, whereas at
darker ambient light levels, display backpanels need less
intensity while the keyboard illumination needs to be
brighter.
By connecting an external resistor from ISRC to GND or
from ISNK to VDD, the current output can be converted into
voltage output.
Housed in an ultra-compact 2mmx2.1mm ODFN clear
plastic package, this device is excellent for power saving
control function in cell phones, PDAs and other handheld
applications.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate - e3 termination finish, which is
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.
