RT9501B

單節(jié)鋰離子電池線性充電控制器; ? 為單節(jié)鋰離子/聚合物電池單元設(shè)計(jì)(4.1V 或 4.2V)\n? 僅需很少的外部元件\n? 預(yù)充電、恒流充電和恒壓充電三種模式\n? 電池溫度監(jiān)測\n? 充電狀態(tài)指示\n? 自動(dòng)復(fù)充\n? 充電終止檢測\n? 電源移除時(shí)自動(dòng)進(jìn)入低功耗睡眠模式\n? MSOP-8封裝\n? 符合 RoHS 規(guī)范，不含鹵素\n;

RT9501 是針對鋰離子/聚合物電池充電使用的線性充電器，適用于空間狹小、成本敏感的應(yīng)用。它包含了充電狀態(tài)指示、充電終止、電池溫度監(jiān)測、高精度電流、電壓調(diào)整等功能，封裝采用 MSOP-8 規(guī)格。它有三種充電模式：預(yù)充電、恒流充電和恒壓充電。當(dāng)電池電壓低于默認(rèn)門限 V_O(MIN) 時(shí)，RT9501 使用一個(gè)很小的電流值對電池狀態(tài)進(jìn)行調(diào)整，此后再用恒定的電流對電池進(jìn)行充電，此電流的設(shè)定利用了一只外部電阻實(shí)現(xiàn)。當(dāng)電池電壓升高到調(diào)整電壓時(shí)，恒壓模式被啟用。電池溫度總是處于被監(jiān)測狀態(tài)下，這是經(jīng)由連接在 TS 引腳的外部熱敏電阻實(shí)現(xiàn)的，只有溫度處于用戶設(shè)定的范圍內(nèi)時(shí)，充電才被容許。
