論述:

CN3722⁽^注1)是一個款就能夠支配太陽光能電池組共電的PWM降壓情勢充電辦理集成電路，具備太陽能電池最大功率點跟蹤功效。CN3722很是適宜對單節或(huo)多節鋰鋰電芯(xin)或(huo)磷酸鐵鋰鋰電芯(xin)的沖電辦，具備封裝(zhuang)的樣(yang)子(zi)小(xiao)，重點元元件少和控(kong)制簡單等特(te)長。

CN3722具備恒流和恒壓充電情勢，很是合適鋰電池或磷酸鐵鋰電池的充電。在恒壓充電情勢，恒壓充電電壓由內部電阻分壓收集設置；在恒流充電情勢，充電電流經由過程一個內部電阻設置。

對深度1充(chong)放電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)池箱箱，當電(dian)(dian)(dian)池箱箱交流電(dian)(dian)(dian)壓(ya)值降至所(suo)軟件(jian)設置的(de)恒(heng)(heng)壓(ya)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)交流電(dian)(dian)(dian)壓(ya)值的(de)66.7%時(shi)，CN3722用所(suo)制(zhi)定(ding)的(de)恒(heng)(heng)流充(chong)電(dian)(dian)(dian)器電(dian)(dian)(dian)流量(liang)的(de)15%對容量(liang)電(dian)(dian)(dian)池中止涓流充(chong)點(dian)。在恒(heng)(heng)壓(ya)充(chong)點(dian)階段性，充(chong)點(dian)直(zhi)流電(dian)(dian)(dian)壓(ya)逐年增加，當充(chong)點(dian)直(zhi)流電(dian)(dian)(dian)壓(ya)增加到所(suo)設立恒(heng)(heng)流充(chong)點(dian)直(zhi)流電(dian)(dian)(dian)壓(ya)的(de)9.5%時(shi)，步入能(neng)充(chong)電(dian)(dian)(dian)竣事(shi)問(wen)題。當傳(chuan)輸(shu)電(dian)(dian)(dian)源線掉電(dian)(dian)(dian)或傳(chuan)輸(shu)電(dian)(dian)(dian)阻(zu)降到電(dian)(dian)(dian)池組電(dian)(dian)(dian)阻(zu)時(shi)，CN3722自主來到低輸(shu)出功(gong)率的(de)就寢態勢。

另(ling)一個藥用(yong)價值(zhi)是指打印輸出低線電(dian)壓鎖存，動力蓄(xu)電(dian)池(chi)環境溫度檢(jian)測，動力蓄(xu)電(dian)池(chi)端過壓擋拆和蓄(xu)電(dian)的情況(kuang)唆(suo)使(shi)等。

CN3722認同16管(guan)(guan)腳(jiao)TSSOP二極(ji)管(guan)(guan)封裝。
