Proximity detection sensors measure reflected infrared (IR) energy to detect the presence of an object or person. The devices include an integrated LED driver and, in some devices, an integrated LED. The proximity detection devices provide four programmable LED drive currents and IR pulse repetitions. The proximity detection circuitry compensates for ambient light, allowing it to operate in environments ranging from bright sunlight to dark rooms. The wide dynamic range allows operation in short-distance detection applications behind dark glass, such as mobile phones. Proximity detection sensors can be used to replace a mechanical switch or to sense human gestures.
