Instructions for BQ24004PWP:

1. Power Supply Connection:

   • Connect the input power supply within the specified input voltage range (4.5V to 28V) to the VIN pin.

2. Output Configuration:

   • The device provides a fixed 5V output on the VOUT pin. Ensure that the load connected does not exceed the maximum output current of 1.5A.

3. Battery Charging Setup:

   • To charge a battery, connect it to the BAT pin. Set the desired charging current using an external resistor or through programming if supported.
   • The default charging voltage is set to 4.2V, suitable for single-cell Li-Ion batteries.

4. Thermal Management:

   • Ensure adequate heat dissipation as the device can operate up to 85掳C ambient temperature. Use heatsinks or thermal vias as necessary.

5. Protection Mechanisms:

   • The device includes built-in protections against over-temperature, over-current, and short circuits. These features are enabled by default.

6. Package Handling:

   • Handle the SOP-8 package with care to avoid damage to pins and ensure correct orientation during PCB assembly.

7. Testing and Verification:

   • After installation, verify the functionality by checking the output voltage and current under different load conditions. Confirm that all protection mechanisms work as expected.
