TP4056 1A LiPo Battery Charging Module with Current Protection – Type-C

The TP4056 and TC4056 are integrated circuits (ICs) designed for charging single-cell 3.7V lithium-ion (Li-Ion) or lithium-polymer (LiPo) batteries. Modules incorporating these ICs, equipped with a Type-C USB interface and current protection features, offer a reliable solution for safely charging such batteries.

Key Features:

• Charging Method: Utilizes a constant-current/constant-voltage (CC/CV) charging approach, ensuring efficient and safe charging cycles.
• Input Voltage: Typically operates with an input voltage ranging from 4.5V to 5.5V, making it compatible with standard USB power sources.
• Charging Current: The default charging current is set at 1A, suitable for batteries with a capacity of 1000mAh or higher. This current can be adjusted by changing the value of the programming resistor (Rprog) on the module.

• Charge Termination Voltage: The module stops charging when the battery voltage reaches 4.2V ±1%, preventing overcharging.
• Protection Features:
  • Overcharge Protection: Prevents the battery voltage from exceeding safe limits.
  • Over-discharge Protection: Disconnects the load if the battery voltage drops below approximately 2.5V, safeguarding against deep discharge.
  • Overcurrent Protection: Limits the output current to prevent damage due to excessive current draw.
  • Short-Circuit Protection: Protects the battery and module from short-circuit conditions.
• Indicators: Equipped with LED indicators—typically, a red LED signifies charging in progress, while a green LED indicates that charging is complete.

Usage Considerations:

• Battery Capacity: It’s advisable to set the charging current to approximately 37% of the battery’s capacity. For instance, for a 1000mAh battery, a charging current of around 400mA is recommended to enhance battery longevity.
• Load Connection: Avoid connecting a load to the battery while it’s being charged, as this can interfere with the module’s ability to detect charge completion, potentially leading to overcharging.

• Wiring: Ensure that connection wires are of appropriate thickness and that all connections are secure to prevent voltage drops and ensure reliable operation.

These modules are widely used in DIY electronics projects, portable devices, and other applications requiring safe and efficient charging of single-cell lithium batteries.
