TMD27713 Proximity Sensor and Digital Ambient Light Sensor Module

TMD27713 is a Ambient Light Sensing, Proximity Detection, and IR LED in a Single Optical Module.

The TMD27713 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.
