Drones and remote-control (RC) systems are very high-speed and compact systems that can be difficult to implement efficiently. The Electronic Speed Controller (ESC) in a drone has high RPM requirements, and fast speed changes in order to operate successfully. As the ESC and camera gimbal motors move to BLDC, it can be challenging to implement the required electronic control is a small, efficient manner. The integration of the PAC family allows a very space-efficient implementation of these systems for battery configurations from 2S to 4S without any other power supply control on the PCB. The PAC® family can also support up to 12S and higher battery stacks with its integrated 70V DC/DC controller. Coupled with the integrated 1A gate drivers and integrated signal conditioning, PAC is an ideal choice for this type of application.
