Description
The TP5000 Lithium Battery Charger Module is an advanced, high-efficiency charging control board based on the TP5000 charging IC. Versatile and compact, it is engineered to charge single-cell lithium batteries—supporting both 3.6V (LiFePO4) and standard 4.2V lithium-ion cells—with a programmable charging current of up to 1A.
Equipped with advanced safety features including battery temperature protection, reverse battery shutdown, and short-circuit protection, this module ensures secure and reliable power replenishment. A dual-color onboard LED provides clear, real-time status telemetry (denoting active charging versus full charge), while built-in automatic recharging automatically tops off the battery if it discharges over time.
Note: Product images are for reference only; actual appearance or labeling may vary slightly based on manufacturing batches. Battery and cables are not included.
Key Features
- Dual-Chemistry Compatibility: Supports both 3.6V lithium iron phosphate (LiFePO4) and standard 4.2V lithium-ion battery cells.
- Programmable Charging Current: Features adjustable charge currents ranging from 0.1A to 2.0A (factory configured for up to 1A).
- Advanced Thermal & Safety Protection: Integrated battery temperature protection, reverse battery shutdown, and short-circuit safeguards.
- Dual-Color LED Telemetry: Onboard multi-color LED visually indicates active charging status and full-charge completion.
- Automatic Recharge Function: Automatically initiates a fresh charging cycle if the battery voltage drops significantly after full charge.
- Ultra-Compact Footprint: Measures just 22 × 15 × 5 mm and weighs a mere 2 grams for effortless integration into tight project enclosures.
Benefits
- Flexible Power Management: Adaptable charging parameters suit various single-cell lithium chemistries for diverse project requirements.
- Enhanced Operational Safety: Multi-layer hardware protection prevents thermal overloads, reverse polarity damage, and short-circuits.
- Autonomous Monitoring: Dual-color LED indicator and auto-recharge functionality eliminate the need for manual oversight during power maintenance.
- Streamlined Prototyping: Miniature board layout requires minimal external wiring, making custom battery box installations clean and professional.
Applications
- Portable Electronic Devices: Custom power management for handheld gadgets, portable tools, and field instruments.
- MP3 & Media Players: Compact charging circuit integration for small audio and multimedia electronics.
- Rechargeable LED Drivers: Battery power and charging board for portable LED work lights and emergency lamps.
- Maker & DIY Battery Packs: Single-cell lithium battery charging module for custom enclosures, Arduino builds, and IoT projects.
