TP4056 Datasheet Explained: Pinout, Charging Modes, and Li-ion Battery Circuit Design

Single-cell Li-ion and Li-Po batteries require controlled constant-current/constant-voltage charging. These cells typically have a nominal voltage of about 3.6–3.7 V and are charged to a maximum of 4.2 V. The TP4056 is a linear charger designed to manage this charging process, with programmable charge current, thermal regulation, charge termination, and temperature monitoring. The TP4056 datasheet […]
