Abstract: Targeting low altitude unmanned aerial vehicle equipment such as industrial inspection, surveying, logistics, etc., relying on 40V ultra-low internal resistance power MOSFET, efficient electric drive and power stability control are achieved, improving the overall endurance and flight reliability of the aircraft.

Application Overview
Industrial drones are widely used in scenarios such as power inspection, environmental surveying, agricultural and forestry operations, logistics transportation, etc. The equipment has extremely high requirements for power response speed, overall lightweight, endurance, and high and low temperature stability. The power efficiency, load capacity, and flight safety factor of unmanned aerial vehicles are directly determined by the conduction loss, heat dissipation performance, and withstand voltage margin of power devices, which are subjected to high-frequency switching, high current transient impact, and frequent start stop conditions for a long time in the driving, battery management, and power switching circuits of unmanned aerial vehicles.
Huaxin Er focuses on the industrial drone field, specializing in 40V ultra-low internal resistance power MOSFETs (typical value of 0.65m Ω), which accurately adapt to the voltage platform and high-power driving requirements of multi string lithium battery drones. The device has extremely low on resistance, significantly reducing conduction losses and overall heat generation under high current conditions, effectively reducing flight power consumption losses, and significantly improving the endurance and load power of unmanned aerial vehicles; 40V high voltage redundancy, capable of withstanding voltage spikes caused by motor reversal and emergency braking, suitable for complex outdoor working conditions, ensuring stable high-frequency PWM speed regulation and linear power output. Compact packaging is suitable for lightweight and miniaturized layout design of unmanned aerial vehicles, perfectly matching the core circuits of industrial unmanned aerial vehicle electromechanical drive, battery protection, and power path switching, helping customers achieve domestic substitution of high-end devices.
The company relies on a mature small signal product line and a continuously expanding MOSFET product matrix to serve the global industrial market with stable quality and flexible supply capabilities. It can provide integrated device support for industrial drone power drive and power management systems, and create cost-effective and highly reliable domestic solutions.
