Overview

NCP383 は単入力デュアル出力ハイサイド配電スイッチです。容量性負荷が重くなりやすくショートが発生しやすいアプリケーション向けに設計されており、非常に RDSON の低い N チャネル MOSFET 2 個が 1 つのパッケージになっています。出力負荷が電流制限閾値を超えた、またはショートが発生した場合、定電流モードへスイッチすることにより、出力電流を目的のレベルまで制限します。電流制限閾値は ILIM と GND の間に配置されたプルダウン抵抗を使って、外部で固定されます。電源スイッチの立ち上がり時間と立ち下がり時間は、電源 ON/OFF 中の電流リンギングが最小になるようコントロールされています。出力電圧が入力電圧よりも高い場合、内蔵の逆電圧検出コンパレータが電源スイッチを無効化し、スイッチの入力側にあるデバイスを保護します。/FLAGx ロジック出力は、過電流、逆電圧、またはおよび過熱状態の間、LOWにアサートします。スイッチは論理イネーブル入力をアクティブ high/low にすることによって制御されます。

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.)
