TP4056 1A Li-ion lithium Battery Charging Module With Current Protection – Mini USB

Description

1. Battery Charging: The primary function of the TP4056 module is to charge single-cell Li-ion and LiPo batteries safely and efficiently. It is designed to charge batteries with a nominal voltage of 3.7V.
2. Charging Current: The module typically supports a charging current of 1A, making it suitable for charging various capacity batteries. Some variants may offer adjustable charging current settings.
3. Input Voltage: The module is often powered through a mini USB connector and can accept input voltages typically in the range of 4.5V to 5.5V. This makes it compatible with USB chargers and power sources.
4. LED Indicators: TP4056 modules commonly feature LED indicators that provide information about the charging status. These LEDs may indicate when charging is in progress, completed, or if there’s a fault.
5. Protection Circuitry: The module includes built-in protection features, such as overcurrent protection, over-temperature protection, and reverse polarity protection. These features help prevent damage to the battery and the charging module.
6. Constant-Current and Constant-Voltage Charging: The TP4056 module typically follows a two-stage charging process: constant-current (CC) and constant-voltage (CV). In the CC stage, the module provides a constant charging current until the battery voltage reaches a specified threshold. Then, it switches to the CV stage to maintain a constant voltage until the battery is fully charged.
7. Automatic Charging Termination: Once the battery is fully charged, the TP4056 module automatically terminates the charging process to prevent overcharging and damage to the battery.
8. Mini USB Connector: The module often comes with a mini USB connector for easy connection to USB power sources, such as USB chargers or computer USB ports.
9. Size and Form Factor: TP4056 modules are compact and typically have a standardized form factor, making them easy to integrate into various electronic projects.
10. Applications: These modules are commonly used in DIY electronics projects, power banks, solar-powered charging systems, and portable devices that require a reliable and safe battery charging solution.
