TP4056 1A Li-ion Lithium Battery Charging Module With Current Protection-(Type C)

Product details The TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection (Type-C) provides a reliable charging solution for single-cell 3.7V Li-ion and Li-Po batteries. It integrates the TP4056 charging controller and DW01A protection circuit to ensure safe and efficient charging while maintaining battery longevity. The module accepts a 5V DC input through a USB Type-C connector or solderable IN / IN− terminals. It delivers a constant current / constant voltage (CC/CV) charging profile with a maximum charging current of 1A, which can be modified by replacing the onboard current-setting resistor. The automatic charge-termination feature stops charging when the battery reaches 4.2V, preventing over-charging damage. The built-in protection circuitry allows the module to supply power through the OUT and OUT− pins while shielding the battery from hazardous conditions such as deep discharge, overload, and short-circuit events. Its compact size makes it suitable for portable electronics, DIY battery packs, IoT devices, power banks, and wearable projects that require safe charging and protection.
