REFLD002
REFLD002 - Reference Design
适用于LiDAR的大功率激光二极管高速驱动EcoGaN™和高速栅极驱动器参考设计
LiDAR传感器不仅适用于车辆的自动驾驶应用，还适用于工业和基础设施领域的众多应用。LiDAR传感器需要具备更远的感测距离和高分辨率，不仅要提高激光二极管的特性，还需要以更快的速度和更高的功率驱动激光二极管。ROHM拥有905nm脉冲的高功率窄线宽激光二极管产品群（RLD90QZWx系列）。另外，ROHM还提供包括可高速驱动的下一代GaN器件“EcoGaN™”和用于GaN HEMT的高速栅极驱动器在内的参考设计，这将非常有助于提高LiDAR传感器的特性（距离、分辨率）。
