Remark

일반 설명

The TMD3702VC is a high sensitivity light-to-digital converter that features ambient light and color (RGBC+IR) sensing in parallel with advanced IR proximity detection. The Ambient light and color sensing function provides four concurrent ambient light sensing channels: Red, Green, Blue, and Clear, which all have a UV/IR blocking filter. The ultra-slim 1.44mm wide package has been designed to accommodate a “single hole” aperture approach and incorporates an IR VCSEL that is factory calibrated driver. This product accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The proximity function synchronizes IR emission and detection to sense nearby objects through photodiode detection of this reflected IR energy. Sensitivity, power consumption, and noise can be optimized with adjustable timing and power and the color photodiodes have dedicated data converters producing 16-bit data output. The prox architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced optical crosstalk noise cancellation, 14-bit data output and interrupt-driven 1.8V I²C communications interface. The proximity engine recognizes detect/release events and produces a configurable interrupt whenever the proximity result crosses upper or lower threshold settings.

TMD2725 Ambient Light Sensor

TMD2725

The device features advanced proximity measurement and digital ambient light sensing (ALS). The package has been designed to accommodate a single small aperture approach. The 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. The ALS detection feature provides photopic light intensity data. The ALS photodiode has UV and IR blocking filters and a dedicated data converter producing 16-bit data. This architecture allows applications to ccurately measure ambient light which enables devices to calculate illuminance to control display backlight.
