World’s best performing light sensor/proximity sensor uses up to five times less board space and six times less current
Intersil has announced the release of the ISL29015 Ambient and Infrared Light to Digital Converter with IR LED Driver. The device debuts as the world’s best-performing integrated light/proximity sensor.
Featuring the capability to sense ambient light as well as perform infrared sensing, the ISL29015 allows precise backlight and display brightness control while also enabling the applied design to utilize proximity estimates. The device is able to operate under harsh lighting conditions, such as under direct sunlight, or behind very dark glass.

The high integration and ultra-small size (2mm x 2.1mm) of the ISL29015 mean that designers can reduce the required footprint of a proximity sensing solution by a factor of five times versus current discrete solutions. In addition, the ODFN packaging of the ISL29015 is fully transparent, allowing for accurate, uncontaminated reading of ambient light.

The ISL29015 is also extremely power-conscious. When actually sensing ambient light for brightness control and infrared for proximity, the device typically requires a supply current of only 50 microamps. This is up to six times less supply current than needed by other light sensing solutions.

The ISL29015 is the first in a series of Intersil products that will include both an ambient light sensor and a proximity sensor.
