WSCE4056B

單節(jié)鋰電線性充電芯片; ? 預(yù)設(shè)4.20V 空載/飽和電壓\n? VIN=0 進(jìn)入待機(jī)模式，待機(jī)電流<3uA\n? 具有BAT-VIN 防倒灌功能\n? 支持對(duì)0V 電池充電\n? 線性充電模式，內(nèi)置1A MOSFET，支持對(duì)0V 電池充電，涓流/恒流/恒壓三段式充電，充電電流外部可調(diào)\n? 短路保護(hù)功能\n? 鋰電池正負(fù)極反接保護(hù)\n? 智能溫控技術(shù)，充電電流會(huì)隨溫度升高而降低，130 度開始下降，最低可降至0\n? 軟啟動(dòng)限制了浪涌電流\n? 可直接從USB 端口給單節(jié)鋰離子電池充電\n? 自動(dòng)再充電\n? 內(nèi)置充電電流會(huì)隨溫度升高而降低\n? 130 度開始下降，最低可降至0\n? 支持1 燈模式和2燈模式\n\n;

WSCE4056B 一款完整的單節(jié)鋰離子電池充電器，帶電池正負(fù)極反接保護(hù)，采用恒定電流/恒定電壓線性控制。只需較少的外部元件數(shù)目使得WSCE4056B 成為便攜式應(yīng)用的理想選擇，可以適用于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。充滿電壓固定于4.20V，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4.20V 之后，充電電流降至設(shè)定值1/10，WSCE4056B 將自動(dòng)終止充電。\n\n當(dāng)輸入電壓（交流適配器或USB 電源）被拿掉時(shí)，WSCE4056B 自動(dòng)進(jìn)入一個(gè)低電流狀態(tài)，電池漏電流在3uA 以下。WSCE4056B 的其他特點(diǎn)包括充電電流監(jiān)控器、欠壓閉鎖、自動(dòng)再充電和兩個(gè)用于指示充電結(jié)束和輸入電壓接入的狀態(tài)引腳。\n\n\n\n
