Overview

NCP361 では、誤った VBUS 動作状態が検出された場合にシステムを出力ピンから切断できます。システムは最大 +20 V の正過電圧から保護されます。PMOS FET を内蔵しているので、外部デバイスが不要で、システム・コストが削減され、アプリケーション・ボードの PCB 領域が縮小します。NCP361 は、入力電圧が過電圧閾値 (OVLO) を超えた場合、即時に出力を入力から切断できます。過電流保護により、充電電流が電流制限を超えると、内蔵 PMOS がオフになります (注文情報のオプションを参照してください)。NCP361 では、ネガティブ・ゴーイング・フラグ (FLAG) 出力により、障害が発生しているとのアラートをシステムに送信します。加えて、1.0 µF 以上のキャパシタによってバイパスされた場合の ESD 保護入力 (15 kV Air) があります。

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.)
