In display management applications, automatically controlling the backlight intensity with an ALS  ensures the best possible user experience while extending battery life.  The TSL2584TSV’s outline and height are approximately half the size of competing ALS devices, making it the world’s smallest ALS.

The company has used its wafer fabrication expertise to include TSV packaging technology as part of its light sensor portfolio. This TSV package technology improves performance by eliminating  use of wire bonds and provides a direct connection from the device I/Os to a solder ball. TSV enhances the device reliability performance with a Moisture Sensitivity Level-1 standard rating, improves Humidity Temperature-Cycling performance while minimizing corrosion resistivity.

The TSL2584TSV’s near-photopic response produces an accurate lux measurement even when mounted behind dark glass. Advanced fabrication technology and the ability to accurately deposit interference filters directly onto the silicon results in a superior performing ALS. Filtering out unwanted IR light enables the sensor to more accurately measure the ambient light thus producing a near-photopic response.
