Commercial & Tactical UAV Systems

Littelfuse Commercial and Tactical Unmanned Aerial Vehicle (UAV) Systems offer solutions for Li-Ion battery protection, battery chargers, and power distribution. These systems provide fuses for input protection/overcurrent protection, MOSFETs for semiconductor switching, and TVS diodes for DC output transient/surge protection. The commercial and tactical UAV systems offer battery protection >60V and provide main-pack fault isolation, battery disconnect/power path control (pre-charge support), and branch circuit overcurrent protection. Typical applications include Intelligence, Surveillance, and Reconnaissance (ISR), military, border surveillance, agriculture, delivery/logistics, inspection, and public safety.
