數(shù)據(jù)： 具有電源路徑管理功能和 I2C 接口的 bq2416xx 2.5A、雙輸入、單節(jié)電池開(kāi)關(guān)模式鋰離子電池充電器 數(shù)據(jù)表 (Rev. G)
bq24160，bq24160A，bq24161，bq24161B，bq24163和bq24168是高度集成的單節(jié)鋰離子電池充電器和系統(tǒng)電源路徑管理器件，適用于采用高容量電池的空間受限型便攜式應(yīng)用。此單節(jié)電池充電器具有雙輸入，可由USB端口或更高功率的輸入電源（即交流適配器或無(wú)線充電輸入）供電，適用于多用途解決方案。兩個(gè)輸入彼此完全隔離，并可以使用I 2 C接口方便地進(jìn)行選擇。
電源路徑管理功能使得bq2416xx能夠?qū)?duì)電池進(jìn)行獨(dú)立充電的同時(shí)通過(guò)一個(gè)高效的直流/直流轉(zhuǎn)換器為系統(tǒng)供電。電源路徑管理架構(gòu)使系統(tǒng)能夠采用有缺陷的電池組或在電池組缺失的情況下運(yùn)行，并且即使在電池完全放電或者無(wú)電池的情況下也可實(shí)現(xiàn)即時(shí)系統(tǒng)啟動(dòng)。
