Tp4056 Datasheet

The TP4056 is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. It incorporates a step-down converter for USB compatibility and a current monitor for precise measurement of the charge current. The TP4056 automatically terminates the charge cycle when the battery is fully charged and enters a low-power standby mode, while also providing a trickle charge to keep the battery topped up. With an input voltage range of 4.5V to 5.5V, the TP4056 is suitable for a wide range of USB power sources. The charger can deliver up to 1A of continuous charge current and offers thermal regulation to keep temperatures within a safe range. In addition, the TP4056 features integrated reverse-blocking protection, over-temperature protection, and battery temperature monitoring. This highly versatile and reliable charger is ideal for a variety of portable electronic devices, including smartphones, tablets, and power banks.
