Overview

NCV7692 は、外部 NPN バイポーラ・デバイスと、LED 駆動に使用する電流を調整するフィードバック抵抗とを組み合わせて使用するデバイスです。ターゲット・アプリケーションは、車載リヤ・コンビネーション・ランプです。シングル・ドライバによって、ユーザはシングル・チャネルをマルチチャネル・システムに追加する柔軟性が得られます。専用の調光機能は PWM 入力ピンを通じて搭載できます。個々のドライバは、オープン・ロードかショートが検出されるとオフになります。LED の輝度レベルは、バイポーラ・トランジスタと直列になっている 2 つの外付け抵抗によってプログラムしやすくなっています。抵抗を使用すると、ユーザは電流の広い範囲にわたってデバイスを使用する柔軟性が得られます。LED の複数のストリングスを NCV7692 デバイス 1 つで動作できます。セットバック電力制限により、過電圧状態での駆動電流が低減します。SOIC−8 パッケージで提供されます。

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.)
