ams TMD2620 Proximity Detection Module
The device is an advanced proximity sensor. 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 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.
ams TMD2725 Ambient Light Sensor
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.
