摘要
针对锂电池的化学特性,给出了一种全CMOS工艺的锂电池充电IC的设计方案。将锂电池充电过程分为涓流充电、常流充电和常压充电3个过程,并为此设计了3段式的充电结构。同时该充电IC还集成了过流检测、温度控制等电路。实验结果表明,其充电过程符合锂电池的化学特性,有效地提高了芯片的能量效率,降低了芯片功耗,缩短了充电时间。
A full COMS Li-ion battery charger has been designed in this paper. A three stage charging strategy has been presented for the character of ripple current charging, large current charging and constant voltage charging in the Li ion battery charging procedue. Mean while, over-charging protecting circuits, and temperature inspecting circuits have been integrated in the IC.
