Power Supply Connection:
- Connect the input power source to the VIN pin.
- Ensure the input voltage is within the specified range (4.5V to 28V).
Battery Connection:
- Connect the battery to the BATT pin.
- The battery voltage should be between 2.5V and 13V.
Charge Configuration:
- Set the charge current using an external resistor connected to the ISET pin.
- Adjust the termination current by configuring the appropriate pins or resistors.
Thermal Management:
- Monitor the device temperature to ensure it does not exceed 120°C, where thermal regulation begins.
System Operation:
- During normal operation, the quiescent current is typically 60μA.
- In shutdown mode, the supply current drops to approximately 2μA.
Efficiency Monitoring:
- The typical efficiency of the charger is around 90%, which can be optimized based on load conditions.
Safety Considerations:
- Always ensure that all connections are secure and within the rated limits to prevent damage to the device or connected components.
