Abstract
An integrated proximity and light sensor includes a first light-emitting device, a second light-emitting device, and a light sensing circuit configured as a single package. The light sensing circuit is configured to control the first light-emitting device and the second light-emitting device to emit light therefrom. Further, the light sensing circuit is configured to detect an ambient light level and to detect a reflection of the light emitted by the first light-emitting device from a surface for proximity detection. The light sensing circuit is also configured to control the second light-emitting device to stop emitting light therefrom for one or more of the ambient light level detection and the proximity detection.
