5V及3.3V MicroMonitor

DS1814 5伏MicroMonitor和DS1819 3.3V MicroMonitor可監(jiān)視微處理器的三個(gè)重要條件：電源、軟件執(zhí)行和外部覆蓋。首先，精密的溫度補(bǔ)償基準(zhǔn)電壓源和比較器電路監(jiān)控VCC的狀態(tài)。當(dāng)出現(xiàn)超出容差的情況時(shí)，會(huì)產(chǎn)生內(nèi)部電源故障信號(hào)，強(qiáng)制復(fù)位為有效狀態(tài)。當(dāng)VCC返回到容差范圍內(nèi)的條件時(shí)，復(fù)位信號(hào)將保持有效狀態(tài)至少140ms，以便電源和處理器穩(wěn)定下來。DS1814/DS1819“A”和“C”執(zhí)行按鈕復(fù)位控制。它們對(duì)按鈕輸入進(jìn)行去抖處理，并生成140ms（最小值）寬度的有效復(fù)位脈沖。DS1814/9“A”和“B”版本執(zhí)行看門狗功能?？撮T狗是一個(gè)內(nèi)部定時(shí)器，如果選通輸入沒有每1; ? 停止并重新啟動(dòng)失控的微處理器\n\n? 在電源瞬變期間對(duì)微處理器進(jìn)行限制\n\n? 發(fā)生電源故障后自動(dòng)重啟微處理器\n\n? 監(jiān)控按鈕的外部覆蓋情況\n\n? 精度為5%、10%或20%（僅限3V）的微處理器電源監(jiān)控\n\n? 無需分立元件\n\n? 20%容差，適用于3.0V系統(tǒng)\n\n? 與MAX823/24/25產(chǎn)品引腳和功能兼容\n\n? 低成本SOT-23-5封裝\n\n? 工業(yè)溫度范圍：?40°C至+85°C;
