TP4056 1A Li-Ion Battery Charger IC
The TP4056 is a 1A Li-Ion Battery Charger IC designed for charging single-cell lithium-ion (Li-ion) or lithium polymer (LiPo) batteries. It offers a highly efficient and reliable solution for charging applications in portable electronics, power banks, and DIY projects. The TP4056 operates using a constant current (CC) and constant voltage (CV) charging profile, ensuring the battery is charged safely and effectively. It provides a 1A charging current with a charging voltage of 4.2V, which is ideal for most single-cell Li-ion batteries. One of its key features is automatic charge termination when the battery reaches full charge, protecting the battery from overcharging. The IC also includes over-voltage, over-current, and thermal protection, ensuring that the battery and circuit remain safe during operation. A status indicator pin allows users to easily monitor the charging process, with an LED signaling the charging status. Additionally, the TP4056 is designed for minimal quiescent current consumption, making it efficient for low-power applications.
