Instructions for Use:

1. Power Supply Connection:

   • Connect the input power supply to the VIN pin. Ensure the voltage is within the range of 2.9V to 5.5V.
   • Ground the GND pin.

2. Output Configuration:

   • Connect the load to the VOUT pin. The output voltage can be set between 3.3V and 5.0V.
   • Ensure the output current does not exceed 1000mA.

3. Battery Management:

   • Connect the battery to the VBAT pin. The battery voltage should be within the range of 2.7V to 5.5V.
   • Set the battery charge current using the IBAT pin. The maximum charge current is 500mA.

4. Shutdown Control:

   • Apply a voltage below 0.8V to the SHDN pin to put the device into shutdown mode.
   • Apply a voltage above 1.2V to the SHDN pin to enable normal operation.

5. Thermal Management:

   • Monitor the temperature to ensure it stays within the operational range of -40°C to 125°C.
   • If the temperature exceeds 125°C, the device will automatically enter thermal shutdown to protect itself.

6. Under-Voltage and Over-Voltage Protection:

   • The device will shut down if the input voltage drops below 2.9V (under-voltage lockout).
   • The device will also shut down if the input voltage rises above 5.6V (over-voltage lockout).

7. Layout Considerations:

   • Use short, wide traces for power and ground connections to minimize inductance and resistance.
   • Place decoupling capacitors close to the power pins to reduce noise and improve stability.

8. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage sensitive components.
