无人机(UAV)

无人机(UAV)具有各种造型和大小。其中比较常见的设计是四旋翼无人机,它包含一个飞行控制器模块和四个独立的电子速度控制器(ESC),用于控制螺旋桨。这些飞行器通常采用电池供电的BLDC,每个电机由六个MOSFET驱动,并可使用USB连接器给电池充电。

功能框图

设计考虑因素

  • 电机必须在高速转弯时连续支撑整个飞行器的重量。
  • ESC需要大小合适,才能确保它们能够提供所需的最大电流

Automotive relay replacement - Reliability meets space savings

A relay is often perceived as the ideal device with perfect input/output isolation. Unfortunately, this is not the case. MOSFETs are rapidly becoming the option of choice offer reliability and space savings.
