TP4056X
The TP4056X is a complete single-cell lithium-ion battery constant current/constant voltage linear charger with reverse battery protection and reverse input power protection. Its bottom-mounted heatsink and ESOP8 package, along with a low external component count, make the TP4056X ideal for portable applications. The TP4056X is suitable for USB power and adapter power. Due to its internal PMOSFET architecture and reverse charge protection, no external isolation diode is required. Thermal feedback automatically adjusts the charge current to limit chip temperature during high-power operation or high ambient temperatures. The charge voltage is fixed at 4.2V, while the charge current can be set externally via a resistor. When the charge current drops to 1/10 of the set value after reaching the final float voltage, the TP4056X automatically terminates the charging cycle. When the input voltage (AC adapter or USB power) is removed, the TP4056X automatically enters a low-current state, reducing battery leakage current to below 1µA. The TP4056X can also be placed in shutdown mode when powered to reduce supply current to 70µA. Other features of the TP4056X include power adaptability, battery temperature detection, undervoltage lockout, automatic recharge, and two LED status pins for indicating charging and completion.
