其中VBAT MIN為(wei)可用(yong)以操(cao)作雙電(dian)源電(dian)子裝置(zhi)100的(de)最小操(cao)作電(dian)池電(dian)壓(ya)，而VRESET為(wei)重置(zhi)電(dian)壓(ya)臨限(xian)。

系統電(dian)壓(ya)節點116處的(de)(de)系統電(dian)壓(ya)VSYS116不應低(di)于(yu)VRESET。因(yin)此，對于(yu)VRESET＝1.8伏(fu)(fu)特(te)(典型的(de)(de)臨限)來說，可(ke)(ke)使(shi)用的(de)(de)最(zui)小電(dian)池電(dian)壓(ya)為VBAT MIN＝1.8伏(fu)(fu)特(te)+0.3伏(fu)(fu)特(te)＝2.1伏(fu)(fu)特(te)。然而，VD122的(de)(de)值(zhi)可(ke)(ke)根據負載、溫度、及其他條(tiao)件(jian)而在廣泛(fan)的(de)(de)范圍內(nei)變(bian)化。因(yin)此，為了提(ti)供可(ke)(ke)靠(kao)的(de)(de)作(zuo)業，一些(xie)已(yi)知的(de)(de)雙(shuang)電(dian)源電(dian)子裝(zhuang)置禁止在電(dian)池電(dian)壓(ya)低(di)于(yu)約2.4伏(fu)(fu)特(te)以下(xia)的(de)(de)裝(zhuang)置作(zuo)業(即(ji)，將(jiang)迫(po)使(shi)裝(zhuang)置關閉)。
