Introduction

AI Translation

TP4056 is a high-performance single-cell lithium-ion battery constant-current/constant-voltage linear charger. Housed in an ESOP8 package with minimal external components, TP4056 is ideal for portable products and supports both USB power and adapter power supplies.

Based on a proprietary internal MOSFET architecture and anti-reverse charging circuit, TP4056 requires no external sense resistors or isolation diodes. When the ambient temperature is too high or in high-power applications, thermal feedback adjusts the charging current to reduce chip temperature. The charge voltage is fixed at 4.2V, and the charge current can be set externally via a resistor. When the charge current drops to 1/10 of the programmed value after reaching the final float voltage, the chip terminates the charge cycle.

When the input voltage is disconnected, TP4056 enters sleep mode and the battery leakage current drops below 1μA. TP4056 can be configured to shutdown mode, in which the quiescent current drops to 35μA.

TP4056 also features battery temperature monitoring, undervoltage lockout, automatic recharge, and two status pins to indicate charge and charge termination status.
