ON Semiconductor


The MicroRB-100xx-MLP products from ON Semiconductor are 1mm light sensors for Light Detection and Ranging (LiDAR) applications. Offering high detection efficiency coupled with single-photon sensitivity, they enable ranging systems to detect low-reflectivity targets over long distances.

The MicroRB-100xx-MLP is part of ON Semiconductor’s RB series of Silicon Photomultiplier (SiPM) sensors. SiPM products are visible and near infrared light sensors which combine high detection efficiency, fast timing, single-photon sensitivity, and low operating voltages of <50V.

The RB series provides higher sensitivity to the red and near infrared regions of the electromagnetic spectrum that are of interest to developers of LiDAR applications. LiDAR systems commonly operate at wavelengths in the range of 830nm to 940nm. In these applications, SiPM sensors are superior to avalanche photodiodes and PIN diodes because of their high gain and single-photon sensitivity.

The RB series SiPM products are suitable for use in LiDAR systems for various applications, including short- and long-range automotive systems, as well as delivery, warehousing and parking systems. Innovative retail, security and people-tracking applications could also benefit from the use of these sensors.

The MicroRB-100xx-MLP devices are backed by compatible power, laser driver and readout solutions also from ON Semiconductor.

The sensor Pin Adapter board is a small PCB which houses the MLP sensor and has through-hole pins to allow its use with standard sockets or probe clips.
