TP5000 Lipo charging module

The TP5000 Lipo charging module is a compact, high-efficiency module designed to charge both 3.7V lithium-ion and 3.2V lithium iron phosphate (LiFePO₄) batteries. It supports a selectable charging voltage of 4.2V or 3.6V, adjustable via a simple solder pad configuration.

Features:

• Supports charging of both Lithium-ion and LiFePO₄ batteries
  
• Auto cutoff when charging completes, protecting the battery from overcharge
• Selectable output voltage(4.2V for Li-ion, 3.6V for LiFePO₄) via solder jumper
• Dual LED charge indicators(Red for charging, Green for full)
• Compact design, suitable for integration into DIY electronics projects
• Performance version supports up to 2A fast charging
• User-configurable charge current via resistor.

Specifications:

• Supported Battery Types:
  
  • 7V Lithium-ion (4.2V full charge)
  • 2V LiFePO₄ (3.6V full charge)
• Charge Voltage:2V / 3.6V (selectable via solder pad)
• Voltage Accuracy:±1%
• Charging Current:
  
  • Default: 1A
  • Max: 2A (adjustable by changing sampling resistor using formula: 0.1V / R = Current)
• Input Voltage:5V – 9V (recommended 5V – 6V; must not exceed 9V)
• Charging Indicator:
  
  • Red LED: Charging
  • Green LED: Fully Charged (requires manual soldering of indicator LED)
• Charging Method:Auto cut-off when fully charged.

 Applications:

1. DIY Battery Charging Projects: Ideal for hobbyists and makers building custom lithium or LiFePO₄ battery chargers.
2. Rechargeable Battery Packs: Can be integrated into portable power banks, flashlight packs, or handheld tools that use 3.7V Li-ion or 3.2V LiFePO₄ cells.
3. Embedded Electronics: Suitable for microcontroller-based systems (Arduino, ESP32, etc.) where compact and reliable battery charging is needed.
4. Battery Maintenance in IoT Devices: Useful for IoT nodes or sensors that require rechargeable battery support with automatic charge management.
