TMF8701-1BM

TMF8701-1BM 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 is ideal for use in the mobile phone market with applications including distance measurement for camera autofocus (laser detect autofocus - LDAF), supporting low-power system operation by enabling high-power components (i.e. 3D facial recognition) only when an object is in the detection range, proximity detection, presence detection - object detection, collision avoidance.

• Small footprint fits in the mobile phone bezel
• 21° FOI, detecting central closest objects
• Time-to-Digital converter (TDC), direct time-of-flight measurement
• Within 5% of measurement (accuracy); no multi-path and no multiple object problems as for iToF
• Single photon avalanche photodiode (SPAD), histogram based architecture
• Better accuracy detects reliably closest object, Min. distance 1mm (black target), max distance 60cm
• Dynamic cover glass calibration, no complex calibration
• Reliable operation under demanding use cases, compensates for dirt on glass
• Reference SPAD, improved accuracy over temperature and life
• OLGA12 package, operating ambient temperature range from -30 to 70°C
