TMD37253M

TMD37253M is an ALS, colour, and proximity sensor module. It features advanced proximity measurement, colour sense (RGBC+IR), and digital ambient light sensing (ALS). The package has been designed to accommodate a “single hole” aperture approach. The slim 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 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. The ALS detection feature provides photopic light intensity data. The application includes ambient light sensing, single hole proximity sensing, mobile phone touch screen disable, and colour temperature sensing to assist backlight, camera, and flash control.
