High-Current Overvoltage Protectors with Adjustable OVLO

General Description The MAX14586/MAX14590 overvoltage protection devices feature a low 48mI (typ) on-resistance (RON) internal FET and protect low-voltage systems against voltage faults up to +36V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent

大電流過壓保護器，提供可調(diào)OVLO

MAX14586/MAX14590過壓保護器具有48mΩ (典型值)低導(dǎo)通電阻(RON)的內(nèi)部FET，為低壓系統(tǒng)提供高達+36V的故障電壓保護。當(dāng)輸入電壓大于過壓門限時，內(nèi)部FET斷開，避免受保護電路損壞。\n\n 可通過外部電阻調(diào)整過壓保護門限，調(diào)節(jié)范圍為4V至20V。當(dāng)OVLO輸入設(shè)置低于外部OVLO選定電壓時，器件自動選擇內(nèi)部精密門限。內(nèi)部過壓門限(OVLO)預(yù)置為典型值7V (MAX14586)或典型值15V (MAX14590)。器件還通過內(nèi)部熱關(guān)斷提供過流保護。\n\n MAX14586/MAX14590采用小尺寸、8引腳TDFN封裝，帶有裸焊盤，工作在-40 ? 為大功率手持設(shè)備提供保護\n? +2.2V至+36V較寬的輸入工作電壓保護\n? 可提供3A連續(xù)電流\n? 集成48mΩ (典型值) n溝道MOSFET開關(guān)\n\n\n? 靈活的過壓保護\n? 可調(diào)整過壓保護觸發(fā)電平\n? +4V至+20V寬范圍可調(diào)OVLO門限\n? 內(nèi)部預(yù)置精密OVLO門限：\n? 7V ±2.9% (MAX14586)\n? 15V ±3.3% (MAX14590)\n\n\n\n\n? 附加保護功能提高系統(tǒng)可靠性\n? 軟啟動降低浪涌電流\n? 內(nèi)部15ms啟動去抖\n? 熱關(guān)斷保護\n\n\n? 最小PCB面積\n? 8引腳TDFN (2mm x ;
