AMS OSRAM GROUP TMF8805-1BM Distance Sensor, 2.5 m, I2C Digital, Time of Flight, 2.7 V to 3.3 V, PCB, TMF8805 Series

TMF8805-1BM is a time-of-flight sensor. It is a time-of-flight (TOF) sensor in a single modular package with associated VCSEL. The TOF device is based on SPAD, TDC, and histogram technology. The device achieves a 2500mm detection range. The application includes distance measurement for camera autofocus (Laser Detect Autofocus - LDAF), supporting low-power system operation by enabling high-power components (i.e. 3D camera) only when an object is in the detection range, presence detection - object detection, and collision avoidance.

• Small footprint fits in the mobile phone bezel
• Detecting central closest objects, no influence on multi object reflections
• Within 5 % of measurement (accuracy); no multipath and no multiple object problems as for iToF
• Time-to-digital converter (TDC) direct time-of-flight measurement
• Single photon avalanche photodiode (SPAD) histogram based architecture
• No complex calibration, dynamic cover glass calibration
• Compensates for dirt on glass, reliable operation under demanding use cases
• Improved accuracy over temperature and life, reference SPAD
• Make better decisions, distance and signal quality reported
• OLGA12 package, operating ambient temperature range from -40 to 85°C
