TP4056 Li Ion Battery Charger IC 1A SOP Package

TP4056 Li Ion Battery Charger IC 1A SOP Package

The TP4056 is a complete single-cell Li-Ion battery charging IC designed for simple, efficient, and reliable battery management. Using a constant-current/constant-voltage (CC/CV) charging algorithm, it provides accurate and safe charging without requiring external control circuitry. The TP4056 is optimized for USB power or adapter-based charging applications and delivers up to 1A charge current.

With its SOP-8 package, built-in power MOSFET, and thermal regulation, the TP4056 ensures stable performance and minimal external components. It includes over-voltage, over-temperature, and charge termination protection, making it ideal for portable electronics and embedded charging systems.
