1. Portable device signal switching: Used for load switches or signal routing in handheld terminals and wearable devices, with ultra-small packaging and low power consumption to extend battery life.
2. Battery protection auxiliary circuits: Acts as an isolation switch in detection or protection paths, working with protection ICs to achieve precise overvoltage and overcurrent shutdown, ensuring system safety.
3. Low-power motor drive: Drives micro DC motors or vibration motors, suitable for smart toys, micro fans, and medical vibrators, supporting PWM speed control.
4. Consumer electronics interface protection: Applied to plug-in detection and on/off control for interfaces such as USB and audio, achieving hot-swap surge suppression and quiescent power management.
5. LED indicator control: Drives low-voltage LEDs or indicator arrays, providing stable switching current and compatible with logic-level direct drive.
6. Level shifting circuits: Used for level matching on low-speed buses such as I2C and SPI, enabling bidirectional logic level conversion and simplifying mixed-voltage system design.
7. Sensor signal conditioning: Acts as an analog switch or sample-and-hold switch in sensor signal chains, with low leakage current ensuring signal acquisition accuracy.
