Proximity Detection
Proximity detection sensors detect and measure reflected infrared (IR) energy to detect the presence of an object or person. The devices include an integrated LED driver and as in the TMD2671 devices, an integrated LED. The proximity detection devices offer a wide range of performance, with 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 cell phones. Proximity detection sensors can be used for a mechanical switch replacement or to sense human gesturing.
