Description
The TMD2771 family of devices provides digital ambient light sensing (ALS), a complete proximity detection system, and digital interface logic in a single 8-pin package. The proximity detector includes a digital proximity sensor, LED driver, and IR LED, which are trimmed to eliminate the need for end-equipment calibration due to component variations. Excellent background light rejection allows the device to operate in environments from sunlight to dark rooms. The wide dynamic range allows for operation in short distance detection such as a cell phone (behind dark glass). An internal state machine provides the ability to put the device into a low-power mode in between ALS and proximity measurements, providing very low average power consumption. The device is particularly useful for display management with the purpose of extending battery life and providing optimum viewing in diverse lighting conditions. Display panel and keyboard backlighting can account for up to 30 to 40 percent of total platform power. The ALS features are ideal for use in notebook PCs, LCD monitors, flat-panel televisions, and cell phones. The proximity function specifically targets near-field proximity applications. In cell phones, the proximity detection can detect when the user positions the phone close to their ear. The device is fast enough to provide proximity information at a high repetition rate needed when answering a phone call. This provides both improved green power saving capability and the added security to lock the computer when the user is not present. The addition of the micro-optics lenses within the device, provide highly efficient transmission and reception of infrared energy, which lowers overall power dissipation. /C0114 /C0114 Texas Advanced Optoelectronic Solutions Inc.

Each device combines one photodiode (CH0), which is responsive to both visible and infrared light, and a second photodiode (CH1), which is responsive primarily to infrared light. Two integrating ADCs simultaneously convert the amplified photodiode currents to a digital value providing up to 16-bits of resolution. Upon completion of the conversion cycle, the conversion result is transferred to the Ch0 and Ch1 data registers. This digital output can be read by a microprocessor where the luminance (ambient light level in lux) is derived using an empirical formula to approximate the human eye response. A fully integrated proximity detection solution is provided with an 850-nm IR LED, LED driver circuit, and proximity detection engine. An internal LED driver (LDR) pin, is connected to the LED cathode (LEDK) to provide a factory calibrated proximity of 100 mm, ± 20 mm. This is accomplished with a proprietary current calibration technique that accounts for all variances in silicon, optics, package, and most important, IR LED output power. This eliminates or greatly reduces the need for factory calibration that is required for most discrete proximity sensor solutions. While the device is factory calibrated at a given pulse count, the number of proximity LED pulses can be programmed from 1 to 255 pulses, which allows different proximity distances to be achieved. Each pulse has a 16 μs period with a 7.2 μs on time. Communication with the device is accomplished through a fast (up to 400 kHz), two-wire I 2C serial bus for easy connection to a microcontroller or embedded controller. The digital output of the device is inherently more immune to noise when compared to an analog photodiode interface. The device provides a separate pin for level-style interrupts. When interrupts are enabled and a pre-set value is exceeded, the interrupt pin is asserted and remains asserted until cleared by the controlling firmware. The interrupt feature simplifies and improves system efficiency by eliminating the need to poll a sensor for a light intensity or proximity value. An interrupt is generated when the value of an ALS or proximity conversion exceeds either an upper or lower threshold. In addition, a programmable interrupt persistence feature allows the user to determine how many consecutive exceeded thresholds are necessary to trigger an interrupt. Interrupt thresholds and persistence settings are configured independently for both ALS and proximity. ams AG Technical content still valid

TAOS143B − SEPTEMBER 2012 The LUMENOLOGY /C0114 Company /C0114 /C0114 Copyright /C0069 2012, TAOS Inc. www.taosinc.com Referring again to Figure 9, the reflected IR LED and the background energy is integrated during the LED On time, then during the LED Off time, the integrated background energy is subtracted from the LED On time energy, leaving the IR LED energy to accumulate from pulse to pulse. After the programmed number of proximity pulses have been generated, the proximity ADC converts and scales the proximity measurement to a 16-bit value, then stores the result in two 8-bit proximity data (PDATAx) registers. ADC scaling is controlled by the proximity ADC conversion time (PTIME) which is programmable from 1 to 256 2.73-ms time units. However, depending on the application, scaling the proximity data will equally scale any accumulated noise. Therefore, in general, it is recommended to leave PTIME at the default value of one 2.73-ms ADC conversion time (0xFF). For additional information on using the proximity detection function behind glass and for optical system design guidance, please see available TAOS application notes. Optical Design Considerations The TMD2771 device simplifies the optical system design by integrating an IR LED into the package, and also by providing an effective barrier between the LED and proximity sensor. In addition the package contains integrated lenses and apertures over both the LED and the sensor, which significantly extends the maximum proximity detection distance and helps to reduce optical crosstalk. Although the package integrates an optical barrier between the IR LED and detector, placing the device behind a cover glass potentially provides another significant path for IR light to reach the detector, via reflection from the inside and outside faces of the cover glass. Because it is cost prohibitive to use anti-reflection coatings on the glass, the faces of the glass will reflect significantly (typically on the order of 4% of the light), and it is crucial that the system be designed so that this reflected light cannot find an efficient path back to the optical detector. See TAOS Application Note DN28: Proximity Detection Behind Glass for a detailed discussion of optical design considerations. ams AG Technical content still valid

The LUMENOLOGY /C0114 Company www.taosinc.com STORAGE INFORMATION Moisture Sensitivity Optical characteristics of the device can be adversely affected during the soldering process by the release and vaporization of moisture that has been previously absorbed into the package. To ensure the package contains the smallest amount of absorbed moisture possible, each device is dry-baked prior to being packed for shipping. Devices are packed in a sealed aluminized envelope called a moisture barrier bag with silica gel to protect them from ambient moisture during shipping, handling, and storage before use. The Moisture Barrier Bags should be stored under the following conditions: Temperature Range < 40° C Relative Humidity < 90% Total Time No longer than 12 months from the date code on the aluminized envelope if unopened. Rebaking of the reel will be required if the devices have been stored unopened for more than 12 months and the Humidity Indicator Card shows the parts to be out of the allowable moisture region. Opened reels should be used within 168 hours if exposed to the following conditions: Temperature Range < 30° C Relative Humidity < 60% If rebaking is required, it should be done at 50°C for 12 hours. The Module has been assigned a moisture sensitivity level of MSL 3. ams AG Technical content still valid
