Industrial GaN Applications: Time of Flight (ToF)/Lidar

Time of Flight (ToF)/Lidar for Robotics, e-Mobility, and Drones
GaN Enables Advanced Autonomy: See Farther, Faster, Better

Gallium Nitride (GaN) transistors and integrated circuits serve as the critical components powering the laser systems in Time-of-Flight (ToF) and lidar technologies. These are essential for a range of applications, including autonomous vehicles, robotics, and drones.

There are two types of time-of-flight systems Direct Time of Flight (DToF) and Indirect Time of Flight (IToF). DToF systems focus on calculating the time interval between the emission of a laser pulse and its subsequent reflection, making them ideal for long-range applications like autonomous driving. On the other hand, IToF systems measure the phase difference between the transmission and reflection envelope and are used often in flash lidar systems and for short-range applications such as collision avoidance.

GaN FETs and ICs excel in generating high-current pulses with extraordinarily brief pulse widths, a requirement for ToF and lidar systems aiming for higher resolution, extended range, and enhanced safety. The compact size, cost-effectiveness, and superior performance of GaN make it the go-to solution for lidar systems striving for quicker, more accurate, and more reliable distance measurement and object detection.

Specific GaN ICs, like the EPC21601 and EPC21603, not only outperform their silicon counterparts but also offer advantages in terms of cost, size, and component count, making them a more efficient and effective choice for modern ToF/lidar systems.
