低成本、上電復位與看門狗控制器

MAX698/MAX699可監(jiān)控微處理器(μP)和數(shù)字系統(tǒng)中的+5V電源。它們在上電、關(guān)斷和低壓掉電條件下提供持續(xù)時間至少140ms的低電平有效復位脈沖。它們無需任何外部元件，也不用進行調(diào)整，以更低的成本提高了電路可靠性。\n\n 除了MAX698的所有特性外，MAX699還提供看門狗輸入以監(jiān)控微處理器活動。如果看門狗輸入(WDI)在1秒內(nèi)未切換，則低電平有效RESET輸出會變?yōu)榈碗娖?。讓WDI保持開路可以禁用看門狗功能。\n\n 兩款器件均采用8引腳PDIP和16引腳0.3英寸寬體小型(SO)封裝，C級器件的額定溫度范圍為0°C至+70°C，E級器件的額定溫度范圍為-40 ? 精密電壓監(jiān)控器\n\n? 電源正常/復位時間延遲\n\n? 看門狗定時器\n\n? 元件數(shù)量最少;
