摘要

本論文的研究方法是參考目前市售的萬能充電器，將其積體化，以標準TSMC 0.5μm 2P4M CMOS製程，實現一個以振盪線圈變換器的馳返式轉換器架構為基礎的可反向三段式線性鋰離子電池充電器。三段式充電器主要以涓流、恆流及恆壓模式依序對鋰離子電池做安全的充電，且機構設計配合可反向功能以達成任何市售型態鋰離子電池皆適用之萬能充電器。整體充電器IC的設計在HSPICE的環境基礎下模擬，輸入電源範圍為2.7V~5.5V，可電阻調整充電電流最大600mA，恆壓為4.2V，並設計過溫度保護及短路保護，靜態功率消耗為1.5mW，而晶片面積(含pad)為1.1×1.2mm2。

The methodology of this essay is to integrate the omnipotent charger presently found on the market by using the standard TSMC 0.5μm 2P4M CMOS process to create a reversible three-stage linear Li-Ion battery charger. The primarily side is a flyback structure base on Ringing Choke Converter. The three-stage charger functions safely in trickle current charging, constant current charging and constant voltage modes progressively. The design of structure combined with the reversible three-stage charger create an omnipotent charger that is adapted to any Li-Ion batteries on the market. The design is simulated under HSPICE environment; Input power range is 2.7V~5.5V. It can adjust the maximum charge current of 600mA by resister, constant voltage is set at 4.2V with built-in over temperature protection and short circuit protection, the quiescent power lose is 1.5mW and chip size (pad included) 1.1×1.2mm2.
