Instructions:
Power Supply Connection:
- Connect the input power supply (VIN) within the specified range (3.0V to 6.0V).
- Ensure the power supply is stable and free from noise.
Battery Connection:
- Connect the battery to the VOUT pin.
- The battery should be capable of handling the maximum charging current (1.5A).
Charging Configuration:
- Set the charging current using an external resistor connected to the ISET pin.
- For typical applications, set the charging current to 1.0A.
Thermal Management:
- Place the device in a well-ventilated area to avoid overheating.
- Monitor the temperature to ensure it does not exceed 150掳C.
Temperature Monitoring:
- Use an external thermistor or other temperature sensor to monitor the battery temperature.
- Ensure the battery temperature remains within the safe range (-40掳C to 85掳C).
Pre-charge and Termination:
- The device will automatically pre-charge the battery if the voltage is below the threshold.
- Charging will terminate when the current drops below the termination current (0.1A) or after 12 hours.
Fault Handling:
- The device will detect and respond to faults within 1.5 seconds.
- Check the fault status and take appropriate action if necessary.
Quiescent Current:
- The device operates with a low quiescent current of 80渭A to minimize power consumption.
Safety Considerations:
- Always follow safety guidelines for handling lithium-ion batteries.
- Do not short-circuit the battery or connect it in reverse polarity.
Testing and Validation:
- Perform initial testing with a known good battery and verify all parameters.
- Validate the charging process and ensure the battery is charged correctly.
