自動車の燃費改善、CO2排出削減、および信頼性向上を達成するという課題に取り組むには、考えられるすべてのエネルギー損失源に目を向け、関連サブシステムの構築方法を再考する必要があります。そうした事情から、油圧による摩擦から生じる損失を低減できる電動燃料ポンプが、機械的なシステムの代わりに導入されています。

電動燃料ポンプはほとんどの場合、ブラシレスDC（BLDC）モータで実装されます。STは、このモータに給電する幅広い3相ゲート･ドライバとパワーMOSFETを提供しています。車載用32bitマイクロコントローラSPC5に専用の電圧レギュレータとパワー･マネージメントICを組み合わせると、高効率ソリューションの設計を簡素化できます。

Based on the EVAL-L99ASC03 evaluation board designed for sensorless 3-phase BLDC motor control, the system features enhanced power management power supply functions including various standby modes. The motherboard, based on an STM8 microcontroller, provides the logic section for monitoring and driving the L99ASC03G 3-phase motor pre-driver assembled in the daughterboard.

ST also provides dedicated user-friendly software with a Graphic User Interface (GUI) that enables the user to set L99ASC03G parameters while displaying device information in real time.

Developers can easily evaluate their brushless DC motor control solution for a variety of circulation and booster pump applications for coolant, water, fuel or oil lines.
