1. **Portable Device Power Management**: Used in power banks, TWS earbud charging cases, and handheld device voltage regulation modules, where low threshold voltage and low static power consumption extend battery life.
2. **Battery Protection Systems**: Acts as a switching element in the charge/discharge path of single-cell lithium batteries, working with protection ICs to achieve fast overcurrent and overvoltage shutdown, ensuring cell safety.
3. **Low-Voltage Motor Drives**: Drives small DC brushed/brushless motors, suitable for micro fans, vibration motors, and toy actuators, supporting low-duty-cycle PWM speed control.
4. **Consumer Electronics Control Units**: Integrated into smart wearables, e-cigarettes, smart locks, etc., for load on/off control and standby wake-up functions.
5. **LED Lighting Constant Current Drives**: Applied in low-voltage LED strips or indicator light modules, acting as a switching transistor to stabilize output current and suppress flicker.
6. **DC-DC Converters**: Used as auxiliary switches or load switches in low-voltage Buck/Boost circuits, reducing conduction losses and adapting to miniaturized power modules.
7. **IoT Sensor Nodes**: Used for power gating in battery-powered wireless sensor networks, enabling low-leakage shutdown in intermittent operation modes.
