Littelfuse Drone Subsystems
Littelfuse Drone Subsystems offer solutions for USB-C PD and Li-ion battery chargers, battery pack systems, and BLDC motors. These subsystems offer fuses for various functions, including AC input overcurrent protection and fault isolation, protection of the battery and downstream controller, pack, wiring, and controller. The drone subsystems provide TVS diodes for primary-side switching transient suppression and cell monitor IC sense line input overvoltage protection. These subsystems are appropriate for various drones, including toy, camera, FPV, enterprise, industrial, ISR, inspection/mapping, agriculture, and heavy lift. Typical applications include delivery/logistics, public safety, border surveillance, and military.
