Overview
The TP4054 is a complete linear Li-ion battery charge management IC featuring a full three-stage charging mode: trickle / constant current / constant voltage. Housed in a compact SOT23-5L package with an integrated MOSFET power output, it requires no external resistors or isolation diodes, minimizing the number of peripheral components and making it easy to design into portable products. The input/output ports support a maximum voltage rating of 11V, making it suitable for various USB power supplies and adapter power environments. Under high-voltage, high-energy operation or elevated ambient temperatures, an advanced thermal regulation circuit automatically controls the charge current to reduce die temperature and improve operational reliability. The charge current of the TP4054 is set by a single external resistor. An advanced charge current monitoring system automatically terminates charging when the float voltage is reached and the charge current drops to 1/10 of the programmed value. The charge termination voltage is set at 4.2V. When the charge supply is removed, the IC automatically enters a low-current state of 1.0μA, minimizing the impact of leakage current on battery capacity. The TP4054 features built-in reverse polarity protection: when the Li-ion battery is connected in reverse, the IC automatically enters a protection state, preventing breakdown or damage, and reducing the risk of accidents caused by battery self-discharge. The TP4054 also features input undervoltage lockout and automatic recharge, with a dedicated pin for an external LED to indicate charging status.
