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)。


  • enables high-speed driving of laser diodes - a key device in lidar applications
  • includes next-gen ecogan™ devices
  • built-in high-speed gate driver for gan hemts (bd2311nvx-c)
  • two circuit types: square wave and resonant
