TMD27123M

TMD27123M is an ALS + proximity sensor module. It features proximity detection and digital ambient light sensing (ALS). The extremely tiny 1mm x 2mm module incorporates an IR VCSEL and factory-calibrated VCSEL 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 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 application includes mobile phone display management, mobile phone and wearable user proximity detection, and wearable ambient light measurement.
