Overview

CAT824 は電子システムの基本的なリセットとモニタ機能を提供します。このデバイスでシステム電圧をモニタして、その電圧がデバイスの指定されたトリップ値に達するまでリセット出力を維持し、デバイスの内部タイマの最小タイマ 140 ms 後までリセット出力アクティブ状態を維持するため、システム電源を安定させることができます。また、CAT824 にはウォッチドッグ入力もあり、システム信号をモニタして、信号がタイムアウト状態になる前に状態を変更できない場合、リセットを発行させるために使用できます。CAT824 は、LOW にプルされる場合、リセットを開始するために使用できるマニュアル・リセット入力も提供します。この入力を押しボタンまたはプロセッサ信号に直接取り付けることができます。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
