Domain and module applications：
1. High-Current DC-DC Converters: Used for synchronous rectification stages or low-voltage, high-current switching nodes. Extremely low on-resistance effectively reduces conduction losses, suitable for high-power-density Buck/Boost designs.
2. Battery Protection and Management Systems: Serves as the main switch path for power battery packs or energy storage systems, supporting 90A-level high current, working with a protection IC for fast overcurrent and overvoltage shutdown to ensure cell safety.
3. Power Tools and Industrial Motor Drives: Drives low-voltage, high-power DC brushless or brushed motors, suitable for drills, saws, fans, and pumps, supporting high-frequency PWM speed control.
4. Automotive Power Systems: For 12V/24V vehicle networks, used in DC-DC conversion, auxiliary load power supply, and motor control, meeting stringent heat dissipation and reliability requirements.
5. Server and Communication Power Supplies: Applied in on-board power modules, hot-swap circuits, and point-of-load power supplies, improving conversion efficiency, reducing temperature rise, and enhancing system stability.
6. Lithium Battery UPS and Storage Inverters: Acts as a battery-side charge/discharge switch, carrying high-rate current, supporting fast switching, and improving overall system efficiency.
7. Electric Bicycle/Motorcycle Controllers: Used for motor drive bridge arms or power switches, adapting to frequent start-stop and stall conditions, providing robust overcurrent capability and thermal margin.
