Description
The TMD2772 family of devices provides digital ambient light sensing (ALS), a complete proximity detection system, and digital interface logic in a single 8-pin surface mount module. The devices are register-set and pin-compatible with the TMD2771 family of devices and include new and improved ALS and proximity detection features. The ALS enhancements include a reduced-gain mode that extends the operating range in sunlight. Proximity detection includes improved signal-to-noise performance and more accurate factory calibration. A proximity offset register allows compensation for optical system crosstalk between the IR LED and the sensor. To prevent false proximity data measurement readings, a proximity saturation indicator bit signals that the internal analog circuitry has reached saturation. The TMD2772 ALS is based on the TAOS patented dual-diode technology that enables accurate results and approximates human eye response to light intensity under a variety of lighting conditions. The proximity detection system includes an LED driver and an IR LED, which are factory trimmed to eliminate the need for end-equipment calibration due to component variations. /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 pin (LDR) is externally connected to the LED cathode (LEDK) to provide a controlled LED sink current. 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. The device is factory calibrated to achieve a proximity count reading at a specified distance with a specific number of pulses. In use, 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

The LUMENOLOGY /C0114 Company www.taosinc.com Figure 8 illustrates light rays emitting from the internal IR LED, reflecting off an object, and being absorbed by the CH0 and CH1 photodiodes. The proximity diode selector (PDIODE) determines which of the two photodiodes is used for a given proximity measurement. Note that neither photodiode is selected when the device first powers up, so PDIODE must be set for proximity detection to work. 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. The proximity gain (PGAIN) determines the integration rate, which can be programmed to 1 ×, 2×, 4×, or 8× gain. At power up, PGAIN defaults to 1× gain, which is recommended for most applications. For reference, PGAIN equal to 8 × is comparable to the TMD2771’s 1× gain setting. During LED On time integration, the proximity saturation bit in the Status register (0x13) will be set if the integrator saturates. This condition can occur if the proximity gain is set too high for the lighting conditions, such as in the presence of bright sunlight. Once asserted, PSAT will remain set until a special function proximity interrupt clear command is received from the host (see command register). 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). In many practical proximity applications, a number of optical system and environmental conditions can produce an offset in the proximity measurement result. To counter these effects, a proximity offset (POFFSET) is provided which allows the proximity data to be shifted positive or negative. Additional information on the use of the proximity offset feature is provided in available TAOS application notes. Once the first proximity cycle has completed, the proximity valid (PVALID) bit in the Status register will be set and remain set until the proximity detection function is disabled (PEN). For additional information on using the proximity detection function behind glass and for optical system design guidance, please see available TAOS application notes. 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 baked prior to being dry packed for shipping. Devices are dry 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. Shelf Life The calculated shelf life of the device in an unopened moisture barrier bag is 12 months from the date code on the bag when stored under the following conditions: Shelf Life: 12 months Ambient Temperature: < 40 °C Relative Humidity: < 90% Rebaking of the devices will be required if the devices exceed the 12 month shelf life or the Humidity Indicator Card shows that the devices were exposed to conditions beyond the allowable moisture region. Floor Life The module has been assigned a moisture sensitivity level of MSL 3. As a result, the floor life of devices removed from the moisture barrier bag is 168 hours from the time the bag was opened, provided that the devices are stored under the following conditions: Floor Life: 168 hours Ambient Temperature: < 30 °C Relative Humidity: < 60% If the floor life or the temperature/humidity conditions have been exceeded, the devices must be rebaked prior to solder reflow or dry packing. Rebaking Instructions When the shelf life or floor life limits have been exceeded, rebake at 50°C for 12 hours. ams AG Technical content still valid
