Overview

NCT375 はシリアルプログラミングが可能な 2 線デジタル温度センサで、過熱/割り込み出力ピンによって限界外状態の信号を出力します。これはオープンドレイン・ピンであり、コンパレータと割り込みのいずれかのモードで動作します。温度測定値は、高分解能 (12 ビット) シグマデルタ AD コンバータ (ADC) を使用してデジタル形式に変換されます。温度範囲 -55°C ～ +125°C で動作します。

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.)
