1 / 44 page  ams Datasheet Page 1 [v1-00] 2016-Jul-12 Document Feedback TSL2671 Digital Proximity Detector 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. The proximity function specifically targets near-field proximity applications. In cell phones, for example, the proximity detection function can detect when the user positions the phone close to their ear. The device is fast enough to provide proximity information at the high repetition rate needed when answering a phone call. This provides both improved green power saving capability and the added security to lock the screen when the user may accidently deploy a touch. Communication with the device is accomplished through a simple two-wire I²C interface with data rates up to 400 kHz. An interrupt output pin is provided for connection to the host processor. This interrupt pin can be used to eliminate the need to poll the device on a repetitive basis. There is also a digital filter that compares the proximity ADC results to programmed values so that an interrupt is generated only upon a proximity event. The TSL2671 is supplied in a very small form factor 2 mm × 2 mm, 6-pin optical package, requiring very little PCB area. Also, the package height is only 0.65 mm high, which makes the TSL2671 suitable for very thin mechanical applications. Ordering Information and Content Guide appear at end of datasheet.
