TP4056 1A Li-ion Lithium Battery Charging Module – Mini USB
Introducing the TP4056 1A Li-ion Lithium Battery Charging Module – Mini USB, a compact and efficient solution for charging your 3.7V lithium batteries. With its onboard Mini USB interface, this module offers convenient charging directly from a computer USB port. Alternatively, you can use an external power source connected to the IN+/IN- pads for flexibility in your DIY projects.
Manufactured with precision and reliability in mind, each module undergoes thorough testing before shipment to ensure optimal performance. The internal PMOSFET architecture eliminates the need for a blocking diode and prevents negative Charge Current Circuit, while thermal feedback regulates charge current to maintain safe operating temperatures.
The TP4056 charging module features a fixed charge voltage of 4.2V and programmable charging current via a single resistor. Charging terminates automatically when the charge current drops to 1/10th of the programmed value after reaching the final float voltage. Additional features include current monitoring, under voltage lockout, automatic recharge, and status indicators for charge termination and input voltage presence.
Please note important considerations for optimal use, including recommendations for charging current based on battery capacity, proper wire gauge and length, and ensuring good contact between the module and battery. Additionally, be aware that this breakout board does not include overcurrent protection.
