具有限流指示功能的雙通道電源開關(guān)

EUP3542是一種雙信道的電源開關(guān)芯片，內(nèi)部集成了兩個100mΩ 的P型MOSFET功率管，每個信道各有一個邏輯使能控制信號。\n當(dāng)負(fù)載超出限制范圍或者有短路情況發(fā)生的時候，芯片會進(jìn)入限流模式，把負(fù)載電流控制在安全區(qū)域內(nèi)，同時拉低限流指示信號OCB(s)，EUP3542和EUP3542-15每個通道的限流電流設(shè)置典型值分別為1A和2.5A。并且具有fold back功能；如果持續(xù)存在超重負(fù)載或者短路情況，芯片內(nèi)部溫度和功耗將迅速上升，芯片將檢測到過溫狀況，并自動進(jìn)入保護狀態(tài)，切斷功率信道以防止芯片損毀；另外，EUP3542還具有檢測輸入電源的功能，功率管會維持關(guān)斷直到電源電壓超過欠壓閾值范圍 ?雙通道100 mΩ High-Side MOSFET\n?1A限流電流，且具有fold-back功能\n?工作電壓范圍:2.7V to 5.5V\n?300μs 輸出電壓上升時間\n?欠壓保護功能\n?15μA 靜態(tài)電流\n?1μA 關(guān)斷電流\n?低電平邏輯使能控制\n?芯片關(guān)斷后沒有反向電流\n?具有延時功能的開漏輸出限流指示信號\n?8引腳SOP封裝\n?符合RoHS規(guī)范及Pb-Free;
