Overview
TP4057 is a complete single-cell lithium-ion battery charge management IC utilizing a constant-current/constant-voltage architecture. Its SOT package and minimal external component count make it an ideal solution for portable applications, compatible with both USB power supplies and adapter power sources. The internal PMOSFET architecture, combined with reverse-charge protection circuitry, eliminates the need for external sense resistors and isolation diodes. Thermal feedback regulates the charge current to limit die temperature during high-power operation or elevated ambient temperature conditions. The charge voltage is fixed at 4.2V, while the charge current is externally programmable via a single resistor. When the charge current drops to 1/10 of its programmed value after the final float voltage is reached, TP4057 automatically terminates the charge cycle. When the input voltage (AC adapter or USB power) is removed, TP4057 automatically enters a low-current state, reducing battery leakage current to below 2uA. TP4057 can also be placed into a shutdown mode, reducing supply current to 25uA. Additional features of TP4057 include a charge current monitor, undervoltage lockout, automatic recharge, and a status pin for indicating charge completion and input voltage presence. The IC integrates a dual-LED charge status indicator, configurable to illuminate a red LED during charging and a green LED upon charge completion.
