3mA-600mA 線性鋰離子電池充電器

TP4065 是一款完整的單節(jié)鋰電池充電器,世界首創(chuàng)帶電池正負(fù)極反接保護(hù)、輸入電源正負(fù)極反接保護(hù)的單芯片,兼容大小3mA-600mA 充電電流。采用涓流、恒流、恒壓控制,SOT23-5 封裝與較少的外部元件數(shù)目使得TP4065 成為便攜式應(yīng)用的理想選擇。TP4065 可以適合USB 電源和適配器電源工作。\n\n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(cè)電阻器和隔離二極管。熱反饋可對(duì)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(duì)芯片溫度加以限制。充滿電壓為：4.2V。充電電流可通過(guò)一個(gè)電阻器進(jìn)行外部設(shè)置。當(dāng)電池達(dá)到預(yù)設(shè)電壓之后,充電電流降至設(shè)定值1/10 ? 兼容大小 3mA-600mA 的可編程充 電電流；\r\n? V CC 輸入端反接保護(hù)；\r\n? 鋰電池正負(fù)極反接保護(hù)；\r\n? 用于單節(jié)鋰離子電池；\r\n? 電源自適應(yīng)；\r\n? 具有可在無(wú)過(guò)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；\r\n? 帶涓流、恒流、恒壓控制；\r\n? 可直接從 USB 端口給電池充電；\r\n? 精度達(dá)到±1%的預(yù)設(shè)充電電壓；\r\n? 最高輸入可達(dá) 8.0V；\r\n? 自動(dòng)再充電；\r\n? 1 個(gè)充電狀態(tài)開(kāi)漏輸出引腳；\r\n? C/10 充電終止；\r\n? 待機(jī)模式下的供電電流為 65μA；\r\n? 軟啟動(dòng)限制了浪涌電流；\;
