Drone Solutions

High-efficiency battery, power-conversion and motor-drive semiconductor solutions for multirotor drones, aerial imaging platforms, inspection UAVs and compact autonomous aircraft.

Drone power and propulsion application

Overview

Drone power architectures must deliver high pulse current to the propulsion system while maintaining clean, stable rails for flight control, sensing, navigation, video and radio subsystems. A practical design combines a protected battery pack, compact DC/DC conversion, low-loss BLDC motor drivers and an MCU-based controller with communication interfaces. Coordinating these blocks helps improve flight time, reduce thermal stress, maintain stable control-loop performance and protect the aircraft during startup, rapid throttle changes, motor stall, battery undervoltage and other abnormal conditions.

About the solution

Coordinated battery, avionics and propulsion power for stable flight performance

The battery pack supplies a high-current propulsion bus for the electronic speed controllers while a dedicated DC/DC converter generates clean low-voltage rails for the flight controller, sensors, navigation receiver, camera and radio link. The MCU controller coordinates throttle commands, motor commutation, current limits, battery thresholds, sensor data and telemetry interfaces. This separation of propulsion and avionics power helps reduce electrical noise and maintains stable control behavior during rapid load changes.

Scalable for consumer, imaging, inspection, mapping and autonomous drone platforms

The same functional platform can be adapted for compact quadcopters, professional aerial cameras, agricultural UAVs, mapping aircraft, infrastructure-inspection drones and autonomous delivery prototypes. Battery voltage, motor current, propeller count, avionics power, payload demand and telemetry interface can be scaled to match aircraft mass, endurance, maneuverability and environmental requirements.

Semiconductor building blocks aligned with every critical drone power path

Battery-path MOSFETs and protection devices, buck and buck-boost converter switches, Schottky diodes, low-resistance motor-drive MOSFETs, three-phase gate drivers, current- and voltage-sense devices, MCU and supervisor functions, level translators, communication interfaces and transient-protection components provide a practical platform for efficient, lightweight and serviceable drone electronics.
