過壓保護(hù)控制器，內(nèi)置斷路開關(guān)

MAX4880過壓保護(hù)控制器具有內(nèi)部限流開關(guān)，可配置為低成本電池充電器。如果輸入電壓大于過壓斷路電平(5.7V)，或者低于欠壓鎖定電平(4.2V)時(shí)，MAX4880會(huì)斷開外部n溝道MOSFET，并將欠壓/過壓標(biāo)志指示(/FLAGV)置為低電平，以便通知處理器。\n MAX4880內(nèi)部限流開關(guān)將電池充電電流限制為525mA。開關(guān)在電池電壓達(dá)到其充滿狀態(tài)(4.2V)時(shí)打開，并將標(biāo)志(/BAT_OK)置位，以便通知處理器。MAX4880包含開關(guān)控制輸入(CB)，可在任意電池電壓下斷開內(nèi)部限流開關(guān)。\n MAX4880還具有內(nèi)置啟動(dòng)延遲功能，使打開MOSFET前適配器電壓達(dá)到穩(wěn)定。其他功能包括：具有1 \n? 高達(dá)28V的過壓保護(hù) \n? 預(yù)設(shè)5.6V過壓斷路電平 \n? 內(nèi)置525mA限流開關(guān) \n? 電池?cái)嚅_(4.2V)檢測(cè)精度為±1.2% \n? 驅(qū)動(dòng)低成本n溝道MOSFET \n? 內(nèi)置50ms啟動(dòng)延遲 \n? 過壓/欠壓故障/FLAGV指示 \n? 電池電壓斷路/BAT_OK指示 \n? 欠壓鎖定 \n? 熱關(guān)斷保護(hù) \n? 微型10引腳TDFN封裝;
