Breaking News | Maxic Launches Long-Range, High-Precision dToF LiDAR Receiver SoC MT3806

Driven by the wave of intelligentization, spatial perception has become a critical performance for smart devices. However, conventional ranging solutions often struggle with accuracy degradation and obstacle avoidance failures in challenging edge cases—such as robotic vacuums navigating black carpets and floor-to-ceiling windows, outdoor mowers detecting lawn boundaries under intense ambient light, or pool-cleaning robots operating in complex underwater refractive environments. The industry is increasingly demanding solutions that can deliver stable and reliable distance information across diverse surface conditions and lighting environments. High-precision, robust long-range ranging capability is rapidly evolving from an optional feature to a standard requirement.

The industry’s technology roadmap is becoming increasingly clear: evolving from triangulation ranging to dToF, from discrete implementations to highly integrated SoCs, and from basic distance measurement to intelligent sensing. In response to the trend, Maxic, leveraging its deep expertise in optical sensing technologies and vertically integrated end-to-end capabilities, has officially launched the new dToF LiDAR receiver SoC, MT3806. Featuring three core advantages—single-photon detection, high-level integration, and strong interference immunity—the MT3806 is engineered to empower the next generation of the long-range sensing market.

MT3806 is a high-performance dToF receiver SoC based on single-photon avalanche diode (SPAD) technology, specifically designed for mid-to-long range, high-precision ranging applications with strong ambient light immunity. The receiver integrates a high-sensitivity SPAD array, a high-precision time-to-digital converter (TDC), an intelligent histogram processing engine, and multi-peak, multi-line detection algorithms, enabling a complete end-to-end processing chain from photon detection to distance calculation on a single chip.

Consequently, MT3806 delivers stable and reliable ranging performance across diverse indoor and outdoor environments. The default ranging distance covers 0.02 m to 15 m, extendable up to 60m with optional configurations. It is well suited for applications including robotic vacuum cleaners, robotic mowers, pool-cleaning robots, service robots, and handheld rangefinders.
