Description

The TP4056 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. Its SOP package and low external component count make the TP-4056 ideally suited for portable applications. Furthermore, the Device can work within USB and wall adapter.

No blocking diode is required due to the internal PMOSFET architecture and have prevent to negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The Device automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value afterthe final float voltage is reached. TP4056 Other features include current monitor, under voltage lockout, automatic recharge and two status pinto indicate chargetermination andthe presence of an input voltage.
