一般說(shuō)明：SP809EK-L-2-9/TR
SP809EK-L-2-9/TR/ SP810低功耗使用微處理器（μP）監(jiān)控電路監(jiān)控μP和數(shù)字電源系統(tǒng)。他們?yōu)閼?yīng)用程序帶來(lái)以下好處通過(guò)消除電路可靠性和低成本外部組件。如果VCC電源電壓降至預(yù)設(shè)閾值以下，然后復(fù)位信號(hào)有效至少140msVCC上升到復(fù)位閾值以上之后。
SP809EK-L-2-9/TR和SP810均采用重置比較器以幫助識(shí)別無(wú)效信號(hào)，持續(xù)時(shí)間不到140毫秒。唯一的他們之間的區(qū)別是他們有一個(gè)低電平有效RESET輸出和低電平有效RESET輸出。低電源電流（1μA）使SP809 / SP810非常適合便攜式設(shè)備。該器件提供3引腳SOT-23封裝包。
