The TMF8701 is a time-of-flight (ToF) distance ranging sensor that uses the time difference between light pulses to measure distance. It provides single-zone detection of an object irrespective of the colour, reflectivity and texture of the object.

The TMF8701 offers a high dynamic range and operates in either a proximity mode (1 –10cm) or a ranging mode (10–60cm) for detection sensing. And the device can make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight.

A built-in histogram is featured to deliver dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters.

The TMF8701 outputs data through an I2C fast-mode communications interface and an integrated microcontroller, which is featured with all algorithms included on-chip with no need for external optics.

Features

  • 21º FOI, detect the object closest to the centre
  • 10–600mm distance sensing
  • Enables dark and sunlight environment distance measurement within ±5%
  • A built-in histogram for compensating for dirt and smudges on the cover glass
  • 940nm VCSEL Class 1 Eye Safety
  • Low power consumption, 940μA power consumption at 10Hz(proximity mode); 26mA power consumption at 60Hz (distance and proximity mode);
  • 0.26μA power-down current consumption (EN=0)
