ams TSL26711. Digital proximity detector, LED drvr., Vdd I2C interface TSL26711

The TSL2671 family of devices provides a complete proximity detection system and digital interface logic in a single 6-pin package. The device 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.
