Remote Control Systems

Littelfuse Remote Control Systems offer solutions for load switching, joysticks, on/off switches, and USB protection. These systems provide the protection IC (eFuse) with USB-C^® for overcurrent, overvoltage, and short-circuit protection for USB input. The remote control systems also provide a TVS diode array for ESD protection of the USB data lines (high-speed interface). These systems support power on/off, mode selection, user interface input, and joystick input/directional control for Unmanned Aerial Vehicle (UAV) operation. The remote control systems offer load switch ICs for power distribution control, subsystem on/off switching, and battery load management. Typical applications include ISR, military, border surveillance, agriculture, delivery/logistics, inspection, and public safety.
