TMD2755 Proximity Sensor Module

ams OSRAM TMD2755 Proximity Sensor Module features proximity detection and digital ambient light sensing (ALS). The ams OSRAM TMD2755 module has a narrow 1.1mm module incorporating an IR VCSEL and factory-calibrated VCSEL driver. Proximity detection provides object detection by photodiode detection of reflected IR energy. 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 ALS and IR photodiodes have dedicated data converters producing 16-bit data. This architecture allows applications to accurately measure ambient light for devices to calculate illuminance to control display backlight.
