Qipan Microelectronics C4050 Battery Management Controller Datasheet
The C4050 integrates charging and boost functions in a single chip for mobile backup power applications. It provides three charging stages—trickle, constant‑current, and constant‑voltage—and includes over‑temperature and over‑current protection.
The device uses an asynchronous boost architecture to deliver up to 7 W of power, supports load detection for low‑power mode, and drives four LED indicators for charge‑level display. It is packaged in a lead‑free QFN 3 mm × 3 mm 16‑lead package and complies with RoHS standards. This manual is written in Chinese.
