由于采用了內(nèi)部PMOSFET架構(gòu)，加上防倒充電路，所以不需要外部檢測電阻器和隔離二極管。熱反饋可對充電電流進(jìn)行自動(dòng)調(diào)節(jié)，以便在大功率操作或高環(huán)境溫度條件下對芯片溫度加以限制。充滿電壓會(huì)因不同的鋰電池而不同，而充電電流可通過一個(gè)電阻器進(jìn)行外部設(shè)置。當(dāng)電池達(dá)到充滿電壓后，充電電流降至設(shè)定值1/10，PT4055C將自動(dòng)終止充電。當(dāng)輸入電壓（交流適配器或USB電源）被拿掉時(shí)，PT4055C自動(dòng)進(jìn)入一個(gè)低電流狀態(tài)，電池漏電流在7uA以下。PT4055C的其他特點(diǎn)包括充電電流監(jiān)控器、欠壓閉鎖、自動(dòng)再充電和一個(gè)用于指示充電結(jié)束和輸入電壓接入的狀態(tài)引腳。
特點(diǎn)
●2.4V鋰電池充電
●鋰電池正負(fù)極反接保護(hù)
●高達(dá)600mA的可編程充電電流
●無需MOSFET、檢測電阻器或隔離二極管
用●于單節(jié)鋰離子電池
●恒定電流/恒定電壓操作，并具有可在無過熱危險(xiǎn)的情況下實(shí)現(xiàn)充電速率最大化的熱調(diào)節(jié)功能
●可直接從USB端口給單節(jié)鋰離子電池充電
●最高輸入可達(dá)7V
●精度達(dá)到±1%的預(yù)設(shè)充電電壓
●自動(dòng)再充電
●1個(gè)充電狀態(tài)開漏輸出引腳
●C/10充電終止
●待機(jī)模式下的供電電流為250uA
●欠壓時(shí)涓流充電
●軟啟動(dòng)限制了浪涌電流
●采用5引腳SOT-23封裝
