Color Light Sensor
艾迈斯半导体新推出的TMD3702VC三合一集成模组采用1.44mm x 2.84mm x 0.65mm封装。智慧手机制造商可用它代替之前尺寸更宽的模组,实施窄边框设计,增大显示幕区域与机身尺寸之间的比例,同时保持重要的红外接近和光感应功能。

该模组集成了一个IR发射器、一个IR探测器、四个颜色传感通道和多个滤光片。凭借艾迈斯半导体专门开发的全新精密光学封装和设计技术,TMD3702VC能够表现出一流的性能。接近感测器采用垂直腔面发射雷射器(VCSEL) 1级人眼安全型940nm发射器,其光学效率比同类设备采用的LED发射器更高。因此,1.8V TMD3702VC主动模式下的平均功耗可保持在非常低的水准。在睡眠模式下,该设备仅消耗0.7µA。

General Description
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.
