TP4056 is a Li-Ion charging and discharging module with a micro USB port. The module protects the lithium-ion battery to overcharge and over-discharge. It is a complete constant voltage/current linear charger of a single cell. It monitors the cell during charging and discharging and after a critical value, it disconnects the circuit.

The module features with internal PMOSFET architecture that neglects the use of blocking diode, externally programmable current by using a single resistor, thermal feedback that regulates the charge current to limit die temperature and onboard charging indication.
