Overview

MAX809/NCV809 および MAX810 は、コスト効率の良いシステム監視回路で、デジタル・システムの VCC をモニタし、必要に応じて、ホスト・プロセッサにリセット信号を送信します。外付け部品は必要ありません。VCC がリセット電圧閾値を下回ってから 10 µsec 以内に、リセット出力がアクティブ化されます。VCC がリセット閾値を上回ったあと、工場でトリミングされたタイムアウト期間中、リセットはアクティブのまま維持されます。MAX810 は、アクティブ HIGH RESET 出力を、MAX809 はアクティブ LOW RESETbar 出力を持ちます。どちらのデバイスも、SOT-23 および SC-70 パッケージで提供されます。MAX809/810 は、VCCline での高速過渡グリッチを排除するように最適化されています。0.5 µA (VCC = 3.3 V) という低供給電流が、これらのデバイスをバッテリ駆動型アプリケーションに最適なものにしています。
