REFLD002 - Reference Design
合用于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想
LiDAR传感器不只合用于车辆的主动驾驶利用，还合用于产业和根本举措措施范畴的浩繁利用。LiDAR传感器须要具有更远的感测间隔和高分辩率，不只要进步激光二极管的特征，还须要以更快的速率和更高的功率驱动激光二极管。ROHM具有905nm脉冲的高功率窄线宽激光二极管产物群（RLD90QZWx系列）。别的，ROHM还供给包含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想，这将很是有助于进步LiDAR传感器的特征（间隔、分辩率）。
