TP4056 Lithium Battery Charger Module With Protection Dual Functions

Description

The TP4056 Lithium Battery Charger Module is a compact and efficient charging circuit designed specifically for charging single-cell lithium-ion (Li-ion) and lithium-polymer (LiPo) batteries. It uses the TP4056 IC, a dedicated lithium battery charging controller, which ensures safe and regulated charging.

Key Features:
1. Micro-USB Input: The module is typically powered through a micro-USB port, making it easy to connect to a standard USB power source (like a phone charger or USB power bank).

2. Constant Current/Constant Voltage Charging: The TP4056 IC employs a two-stage charging process: it initially charges the battery with a constant current until it reaches the battery’s rated voltage (usually 4.2V), then switches to constant voltage to ensure a safe full charge.

3. Overcharge Protection: The module is designed to stop charging once the battery reaches its fully charged voltage (4.2V) to prevent overcharging, which can damage the battery.

4. Integrated Protection Circuit: Many versions of the module also feature built-in protection against overcurrent, short-circuit, and overvoltage, providing additional safety for both the battery and the charger.

5. Status Indicators: The module usually includes two LED indicators: one for power (typically red) and one for charging status (usually blue or green).

6. **Compact and Easy to Use: The small form factor (about 2.5 x 1.5 cm) and ease of integration into DIY projects make it popular in a variety of applications, such as powering small electronic projects or devices that require rechargeable batteries.

Applications:
– DIY electronics: Powering projects like Arduino boards, small robots, or sensors.
– Portable devices: Charging for portable power banks or gadgets that require a small rechargeable battery.
– Battery-powered projects: Ideal for powering low-power, battery-operated devices in a range of applications, including wearables, LED lighting, and more.

Charging Current:
Typically, the TP4056 module can handle charging currents around 1A, but some versions of the board may allow adjusting this current depending on the needs of the specific battery. Charging rate is generally dependent on the size and type of the battery.

Conclusion:
The TP4056 module is a simple, reliable, and cost-effective solution for charging single-cell lithium batteries. It’s widely used in hobbyist and maker communities for building rechargeable battery-powered devices due to its ease of use, safety features, and low cost.
