Bochi Xin CT6302B Power Management Chip Datasheet
The CT6302B integrates a linear high‑current charging circuit (up to 1 A) and an asynchronous boost converter that provides a regulated 5.2 V output. It includes battery‑voltage detection, key‑press power control, LED illumination control, and multiple protection functions such as over‑temperature and over‑current protection.
Designed for large‑capacity single‑cell or parallel lithium‑ion/polymer batteries, the chip operates from 3.0 V to 5.5 V input and supports automatic on‑off behavior when an adapter is connected or when no load is present for more than 16.8 s. The datasheet provides pin descriptions, application schematics, electrical parameters, and PCB layout guidelines. This manual is written in Chinese.
