Tp4056 Datasheet

The TP4056 is a highly integrated single-cell Li-ion battery charger IC that uses a constant-current/constant-voltage (CC/CV) charge algorithm with programmable charge currents up to 1A. It is designed to work with various input power sources, including USB ports and solar panels. With a wide input voltage range of 4.5V to 5.5V, the TP4056 provides efficient and reliable charging for 3.7V Li-ion batteries. The built-in thermal regulation prevents overcharging and overheating, ensuring the safety and longevity of the battery. This IC features an integrated precision voltage reference, reverse battery protection, and automatic recharge. The compact and easy-to-use DIP-8 package makes it suitable for a wide range of applications, including power banks, portable devices, and battery-operated systems. The TP4056 includes an LED indicator that provides clear charging status information, making it convenient for users to monitor the battery's charge level. Its low external component count and simple application circuit make it an ideal choice for cost-effective battery charging solutions.
