TP4056 Typical Applications

The charging current of the module is set to 1A by default. However, it can be changed by altering the resistor RPROG (R3 on the module) in the circuit diagram. The datasheet for the TP4056 datasheet may be seen below for more information.

TP4056 Application Circuit

The module will automatically stop charging after the Lithium battery is fully charged, and the Red LED will turn off and the Green LED will turn on to signal completion. As illustrated in the pin diagram above, the circuit can now be connected to the Circuit (Load) that must be powered by this battery. The voltage of the battery will be monitored as it is consumed by the circuit by the module (load). When it falls below the crucial level (3.7V), the module will separate your battery from the load and safeguard it from over-discharge.

Where to Use TP4056

It is ideal for charging 18650 cells and other 3.7V batteries because of its capacity to supply 4.2V. Because it only requires a few external components, it can be used in portable applications. Mobile phones, tablets, laptops, cameras, power banks, and a variety of other electronic gadgets all consume batteries; hence this module is used to charge them. This module can also be utilized with a USB port and a wall adaptor.

How to use TP4056

The TP4056 module is powered by a 5V supply from a micro USB cable or the IN+ and IN- solder pads. For the charger to correctly charge a battery connected at the output terminals, a current of at least 1A is necessary. Connect the B+ and B- connections to the cell you want to charge. The battery's power is supplied through the OUT+ and OUT- pads. As a result, if you're running a load, you can attach it to these two pads. But remember to disconnect the load from the module if you're charging a cell.
