Instructions:

1. Connect the Input Supply: Connect the input supply voltage within the range of 4.5V to 16V to the VIN pin.
2. Connect the Battery: Ensure the battery is a Li-Ion or Li-Polymer type and connect it to the BATT pin.
3. Set Charging Current: Use an external resistor connected between PROG and GND to set the desired charging current.
4. Enable Power Path Management: The device automatically manages power path from the input supply to the system load.
5. Monitor Charge Status: Use the STAT1 and STAT2 pins to monitor the charge status and fault conditions.
6. Thermal Considerations: Ensure adequate heat dissipation, especially when operating at higher ambient temperatures.
7. Shutdown Mode: Place the device in shutdown mode by pulling the EN pin low to reduce quiescent current.
