TMD37024VCM

TMD3702VC Narrow ALS, Color and Proximity Sensor Module The TMD3702VC features proximity detection, color sense General Description (RGBC+IR), and digital ambient light sensing (ALS). The extremely narrow 1.44mm module incorporates an IR VCSEL and factory calibrated VCSEL driver. The proximity detection feature provides object detection (e.g. mobile device screen to users ear) by photodiode detection of reflected IR energy (sourced by the integrated VCSEL). Detect/release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features a wide range offset adjustment to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction. The color photodiodes have UV and IR blocking filters and dedicated data converters producing 16-bit data. This architecture allows applications to accurately measure ambient light which enables devices to calculate illuminance and color temperature to control display backlight and chromaticity.
