**Precautions for use:** 1. Operate strictly in accordance with the rated voltage and current to avoid exceeding the specified values. 2. The package is DFN8 (3X3), pay attention to heat dissipation and layout design to ensure normal operating temperature. 3. Consider the threshold voltage Vth=1.2V in the design to ensure the appropriate signal level. 4. It is necessary to select appropriate protection measures according to the specific application scenario to prevent overcurrent and overvoltage.
