MT3801 integrates SPAD, algorithm processing module, Cortex M0 core, etc. It is small in size, supports multiple voltage interfaces, low power consumption, and has a built-in temperature sensor to ensure detection accuracy when the temperature changes.
Its ranging range is 0.02m to 5m, with an error of less than 4%, and can be widely used in smart phones, sweeping robots, smart toilets and other fields.
As a major breakthrough in the field of sensors, dToF technology is showing its importance and strong application potential in consumer electronics, automotive and industrial automation.
Compared with iToF (indirect time of flight) technology, dToF calculates the distance by directly measuring the time difference from the emission to the reception of a single photon, eliminating the complex phase solution process, thus achieving a qualitative leap in measurement accuracy and anti-interference ability.
MT3801, the latest dToF sensor with fully integrated precise direct time of flight ranging, is launched by Maxic. It performs precise ranging based on the single photon time of flight, and the ranging range supports up to 5m. It also integrates SPAD, algorithm processing module, Cortex M0 core, 940nm VCSEL and optical filter, and can be widely used in mobile phones/pads, sweepers, hair dryers, faucets, smart toilets, projectors, drones and other fields.
