Overview

CAT874は、プッシュボタン入力や電話のマイクロコントローラユニットで、スマートフォンの電源をオン／オフするために設計されたスイッチコントローラです。CAT874は、2個の入力を監視し、PWR_ON入力がアクティブ（ロジックLOW）になった後、または出荷時にプリセットされた最小時間後に、 アクティブHIGH出力を出力します。最小タイムアウト時間前にアクティブ状態から入力を解除すると、内部タイマがリセットされ、タイマが最初からカウントダウンを再開する前にアクティブに戻す必要があります。この出力は、次のPWR_ONがHighからLow、またはVCHGがLowからHighに遷移するまで、Highを維持します。CAT874のプッシュプル出力は、最大3 mAの電流をシンクできます。
