5V、經(jīng)濟型復(fù)位芯片

DS1233經(jīng)濟型復(fù)位可以為微處理器監(jiān)視兩個重要條件：電源異常及外部數(shù)據(jù)覆蓋故障。精密的溫補基準和比較器用于監(jiān)視電源狀態(tài)(VCC)。一旦檢測到電源超出容差范圍，內(nèi)部將產(chǎn)生電源失效信號、強迫置為復(fù)位狀態(tài)。當VCC恢復(fù)到正常條件時，復(fù)位狀態(tài)將持續(xù)保持大約350ms，以便電源和處理器達到穩(wěn)定狀態(tài)。DS1233的第二個功能是手動復(fù)位控制，DS1233提供按鍵去抖，釋放復(fù)位前產(chǎn)生350ms的復(fù)位脈沖。 ? 電源失效后可自動重啟微處理器\n? 監(jiān)控按鈕可用于防止外部數(shù)據(jù)覆蓋\n? 內(nèi)部電路消除按鈕開關(guān)抖動\n?

5V EconoReset

DESCRIPTION The DS1233D EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active state. When V
