The TP4056 is a commonly used lithium-ion battery charger module that is designed to charge single-cell lithium-ion or lithium-polymer batteries while providing overcharge and over-discharge protection. The protection features help ensure the safe and reliable charging of lithium batteries. Here are the key features of a typical TP4056 lithium battery charger module with protection:

1. **Charging IC (TP4056):** The module is built around the TP4056 lithium battery charging IC, which manages the charging process.

2. **Single-Cell Battery Charging:** The TP4056 is designed to charge a single lithium-ion or lithium-polymer battery cell, which is commonly used in many portable electronic devices.

3. **Micro USB or Mini USB Input:** The module typically has a micro USB or mini USB input port for connecting to a power source, such as a USB wall adapter, power bank, or a computer’s USB port.

4. **Charging LED Indicator:** There is usually an LED indicator that shows the charging status. The LED may change color or blink to indicate charging, completed charging, or an error condition.

5. **Protection Circuitry:**
– **Overcharge Protection:** The TP4056 module includes protection against overcharging the battery. When the battery voltage reaches the preset threshold, the charging process is stopped to prevent damage to the battery.
– **Over-Discharge Protection:** The module also has over-discharge protection to prevent the battery from discharging below a safe voltage level, which can damage the battery.

6. **Battery Connection:** The battery connects to the module using two terminals, typically labeled as “BAT” and “B-.”

7. **Output Connection:** The module provides an output for connecting the battery to your application or device, typically labeled as “OUT” and “B+.”

8. **Charge Current Setting:** Some TP4056 modules allow you to set the charging current using a resistor or a built-in potentiometer. This feature enables you to adjust the charging rate based on your battery’s specifications.

9. **Input Voltage Range:** The module can usually accept a wide input voltage range, often from 4.5V to 5.5V, which makes it compatible with various power sources.

10. **Thermal Shutdown:** TP4056 modules may include thermal shutdown protection to prevent overheating during the charging process.

11. **Applications:** TP4056 modules with protection are widely used in DIY electronics projects, portable battery chargers, power banks, and other applications where single-cell lithium-ion or lithium-polymer batteries need to be safely charged and protected.

When using a TP4056 module with protection, it’s important to follow the manufacturer’s recommendations, especially when setting the charging current and ensuring proper connections. These modules provide a cost-effective and straightforward solution for safely charging lithium batteries, making them popular choices in the maker and hobbyist communities.
