概要
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.

Evaluation Kit for TSL2671
TSL2671EvalKit
The TSL2671 Evaluation Kit comes with everything needed to evaluate the TSL2671 proximity and ambient light sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TSL2671 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the proximity and ALS sensor settings as the PIC takes the TSL2671 I2C digital outputs to calculate proximity and ALS illuminance in lux approximating the human eye response.
Please note that ams-OSRAM AG is discontinuing production of TSL2671.

TMD2620 Proximity Detection Module
TMD2620
The device is an advanced proximity sensor. The slim module incorporates an IR LED and factory calibrated LED driver. The proximity detection feature provides object detection (e.g. mobile device screen to user’s ear) by photodiode detection of reflected IR energy (sourced by the integrated LED). Detect/Release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction.
TSL2740 Ambient Light Sensor
TSL2740
The TSL2740 includes both proximity detection and very-high sensitivity light-to-digital converter ambient light sensing (ALS) features. The proximity detection feature provides object detection using photodiode detection with reflected IR energy. The detect/release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction. The ALS feature approximates the human eye response to light intensity under varying lighting conditions and transforms this light intensity to a digital signal output capable through a 1.8V I²C interface. The ALS sensor features 2 output channels, a visible channel and an IR channel. The visible channel has a photodiode with a photopic Interferometric UV and IR blocking filter and the IR channel has a photodiode with an IR pass filter. Each channel has a dedicated integrating data converter which converts photodiode current into a 16-bit digital output. This digital output can be interfaced with a microprocessor where illuminance in lux is derived to accurately measure ambient light to control a displays baklight.
