 Description |
|
|
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. |
