Power Supply Connection:
- Connect the input voltage (VIN) to a power source within the operating range of 3.0V to 5.5V.
Battery Connection:
- Connect the battery to the VBAT pin. Ensure the battery voltage is within the operating range of 2.9V to 4.4V.
Charge Current Setting:
- Use external resistors to set the charge current (ICHG). The typical charge current can be set up to 1000mA.
Pre-Charge and Termination Currents:
- The pre-charge current (IPRE) is fixed at 200mA, and the termination current (ITerm) is fixed at 100mA. These values cannot be adjusted externally.
Thermal Regulation:
- Monitor the junction temperature to ensure it stays below 80°C for optimal performance.
Quiescent and Shutdown Currents:
- When no load is connected, the quiescent current is approximately 60μA.
- In shutdown mode, the current draw from VIN should be around 0.1μA when VIN is set to 5V.
Safety Considerations:
- Always ensure proper heat dissipation and use appropriate protection circuits to safeguard against overvoltage and short circuits.
Programming and Configuration:
- Refer to the specific datasheet for detailed programming instructions and configuration settings for advanced features like status monitoring and fault protection.
