Mouser – Complete proximity detection device with digital interface logic (AOS TSL2671)Jul 26 2012 - Switches, Relays & Onboard [More Switches, Relays & Onboard Articles]
Mouser now offers from stock the AOS TSL2671 digital proximity detector, which provides a complete proximity detection system and digital interface logic in a single 6-pin package.
The TSL2671 includes a digital proximity sensor with integrated LED driver for the required external IR LED. The proximity function offers a wide range of performance, with four programmable LED drive currents and a pulse repetition range of 1 to 32 pulses. The proximity detection circuitry compensates for ambient light, allowing it to operate in environments ranging from bright sunlight to dark rooms. This wide dynamic range also allows operation in short-distance detection applications behind dark glass, such as cell phones. An internal state machine provides the ability to put the device into a low-power mode for very low average power consumption.
Typical applications include cell phone touch screen disable, notebook / monitor security, automatic speakerphone enable and automatic menu pop-up.Electropages - Electronics Components News, From Leading Electronics Distributors. More news from Mouser
