BD18337EFV-M
內置熱分散電路 40V 150mA 4通道　車電用LED驅動器

BD18337EFV-M是4通道線性LED驅動器，可通過1個引腳控制多個輸出的熱分散。不僅可顯著減少部件數量和安裝面積，還非常有助於平台化擴展機型的汽車LED燈驅動模組電路板的通用化設計。可用於車後燈(刹車燈、尾燈)、霧燈、轉向燈、牌照燈、日間行車燈(Daylight Running Lamps)等汽車和機車領域的眾多LED燈驅動。
產品內置LED開路檢測功能、OUTx（x=1~4）引腳輸出接地故障保護功能、過電壓靜音功能及熱關斷功能，可實現高可靠性。連接於輸出引腳的LED如果是2段的，請使用BD18347EFV-M；如果是3段的，請使用本BD18337EFV-M。
