GalaxyElec TP5100 Lithium Battery Charge Management Module User Manual

1. Продукт закончилсяview

The GalaxyElec TP5100 is a versatile double switch buck charge management chip designed for 8.4V dual-cell and 4.2V single-cell lithium batteries. Its compact QFN16 package and simplified external circuitry make it suitable for portable equipment requiring high-current charging. The module integrates various protection features, including input overcurrent, undervoltage, over-temperature, short-circuit, battery temperature monitoring, and reverse battery protection.

Поддерживает широкий диапазон входных громкостей.tage range of 5V-18V and features a three-phase charging process: trickle charge, constant current, and constant voltage. The pre-charge and trickle charge currents are adjustable via an external resistor, with a maximum charge current of up to 2A. The 400kHz switching frequency allows for smaller external components and efficient heat management during high-current charging. The built-in power PMOSFET and anti-intrusion circuit eliminate the need for external Schottky diodes for reverse protection.

4. Настройка и подключение

Before connecting the TP5100 module, ensure all power sources are disconnected. Observe proper polarity for all connections to prevent damage to the module or connected devices.

4.1 Подключение входного питания

• Connect a DC power source (5V-18V) to the input terminals (typically marked VIN+ and VIN- or similar).
• Обеспечьте входной объемtage is within the specified range to avoid overvoltage или undervoltagе условия.

4.2 Подключение батареи

• Connect the lithium battery (single cell 4.2V or double cell 8.4V) to the battery terminals (typically marked BAT+ and BAT-).
• Verify the battery type and voltage match the module's configuration (single or double cell).
• The module automatically detects the battery configuration (4.2V or 8.4V) and adjusts charging parameters accordingly.

4.3 Output Connection (Optional)

• If the module provides a separate output for load, connect your load to these terminals.
• Note that the PWR_ON pin can be used for switching control of the power battery. Consult the datasheet for specific implementation details.

5. Инструкция по эксплуатации

Once properly connected, the TP5100 module will begin the charging process automatically.

5.1 Процесс зарядки

• Подзарядки: Если уровень заряда батареиtage is very low, the module will start with a low current trickle charge.
• Постоянный ток (CC): Как только батарея voltage reaches a certain threshold, the module switches to constant current charging, delivering the programmed charge current.
• Постоянный объемtagе (резюме): As the battery approaches full charge, the module enters constant voltage mode, reducing the current until the battery is fully charged.

5.2 светодиодных индикатора

• Красный светодиод: Typically indicates charging in progress.
• Зеленый светодиод: Typically indicates charging complete or standby.
• Note: Specific LED behavior may vary slightly depending on the module's exact implementation.

5.3 Регулировка тока

The charge current (0.1A-2A) and precharge current (10%-100%) are programmable via external resistors. Refer to the TP5100 datasheet for detailed resistor value calculations and connection diagrams for current setting.

6. Техническое обслуживание и уход

• Содержите модуль в чистоте, защищая его от пыли и влаги.
• Не подвергайте модуль воздействию экстремальных температур или прямых солнечных лучей.
• Do not apply excessive force or bend the PCB.
• Ensure adequate ventilation, especially during high-current charging, to prevent overheating.
• Regularly inspect connections for looseness or corrosion.

7. Поиск Неисправностей

7.1 Module Not Charging

• Проверьте входное напряжение: Убедитесь, что входной объемtage is within the 5V-18V range and the power supply is capable of providing sufficient current.
• Проверьте подключение аккумулятора: Ensure the battery is correctly connected with proper polarity to the BAT+ and BAT- terminals.
• Батарея Voltage: Если уровень заряда батареиtage is extremely low, the module might be in a protective state or require a very slow trickle charge.
• Светодиодные индикаторы: Observe the LED status for any error indications.

7.2 Перегрев

• Reduce Charge Current: If the module is getting excessively hot, consider reducing the programmed charge current.
• Улучшите вентиляцию: Ensure the module has adequate airflow.
• Контрольная нагрузка: If an external load is connected, ensure it is not drawing excessive current.

7.3 Incorrect Charge Voltage

• Конфигурация батареи: Confirm the module is correctly configured for a single (4.2V) or double (8.4V) cell battery. The TP5100 typically auto-detects, but ensure the battery type is compatible.
• Неисправная батарея: A damaged or unbalanced battery pack can lead to incorrect charging.
