方向指示器、ヘッドライト、テールランプなどの車載用エクステリア照明システムは、あらゆる自動車に装備されています。安全性や快適性の向上を実現させながら、より洗練された車体デザインを可能にするため、自動車には、高輝度放電ランプ(HIDまたはキセノン)や発光ダイオード(LED)を使ったアダプティブ・フロント・ライト・システムが採用されてきています。

スマート・ヘッドライト・システムには、高度な診断機能を備えた高効率LED駆動ソリューションを使用する必要があります。ダイナミック照明を実装したハイエンドのシステムでは、ヘッドライト・レベリングやベンド・ライト制御も必要です。

STの車載用製品ポートフォリオは、高出力フロント・ビーム・ランプからデイタイム・ランニング・ライトまでのエクステリア照明システム向けのハイサイド/ローサイド・ドライバ、サイド・ライトおよび後方ライト向けに使用される低消費電力負荷、さらには先進的なレギュレータやコスト最適化されたマイクロコントローラを含み、高効率かつ信頼性の高いLED照明モジュールの開発を可能にしています。

    • Demonstrates pre-configured patterns (with adjustable brightness/speed) such as rolling text, wave effect, dot sequence, etc.
    • On-board buttons to switch between the demos
    • Potentiometer as a slider to control speed or brightness of the pattern
    • Open circuit, short circuit using open-circuit/short-circuit jumpers
  • GUI mode:
    • All the features present in stand-alone mode can be controlled using the GUI
    • Global brightness control to change the brightness of all channels
    • Frame programming mode and 4 predefined presets with variable transition time between frames
    • Open/short error detection and representation on the GUI
    • Error detection in “no loop” and in loop of 0.5 s and 1 s
  • RoHS compliant
