Surge Stopper with Ideal Diode

DESCRIPTION The LTC?4364 surge stopper with ideal diode controller protects loads from high voltage transients. It limits and regulates the output during an overvoltage event, such as load dump in automobiles, by controlling the voltage drop across an external N-channel MOSFET pass device. T

具有故障閂鎖功能的浪涌抑制器

LT4356-3 浪涌抑制器可保護(hù)負(fù)載不受高電壓瞬態(tài)的影響。它可在過壓事件（例如汽車負(fù)載突降）期間通過控制外部 N 通道 MOSFET 來調(diào)節(jié)輸出。輸出將被限制為安全值，從而允許負(fù)載繼續(xù)正常運(yùn)行。LT4356-3 還可監(jiān)控 VCC 和 SNS 引腳之間的電壓降，以防止發(fā)生過流故障。內(nèi)部放大器可將電流檢測電壓限制為 50mV。在任一故障條件下，將會(huì)根據(jù) MOSFET 應(yīng)力按比例反向啟動(dòng)計(jì)時(shí)器。如果計(jì)時(shí)器終止，F(xiàn)LT 引腳將會(huì)拉低以警告即將關(guān)斷。如果該狀況持續(xù)存在，則會(huì)關(guān)閉 MOSFET，直到 SHDN 引腳暫時(shí)拉低。\n\n 該輔助放大器可用作電壓檢測比較器或用于驅(qū)動(dòng)外部 PNP 調(diào)整 ? 可阻止高電壓浪涌\n? 可調(diào)輸出鉗位電壓\n? 過流保護(hù)\n? 寬工作范圍：4V 至 80V\n? 反向輸入保護(hù)高達(dá) –60V\n? 7μA 低關(guān)斷電流\n? 可調(diào)閂鎖故障計(jì)時(shí)器\n? 控制 N 通道 MOSFET\n? 關(guān)斷引腳可承受 –60V 至 100V 電壓\n? 故障輸出指示\n? 適用于電平檢測比較器或線性穩(wěn)壓器控制器的輔助放大器\n? 采用 12 引腳 4mm × 3mm DFN、10 引腳 MSOP 和 16 引腳 SO 封裝;
