Description
BD83733HFP-M是50V高耐壓LED源極驅動器。恆電流輸出可進行PWM調光，最適合車用LED驅動。內建LED開路/短路檢測、LED電流降額功能，可實現高可靠性。通過使用已獲得專利的PBUS功能，在使用多個本IC驅動多列LED時，即使當某列LED發生了開路/短路，也可以對全部LED進行統一的OFF控制。輸出IOUT端子上連接2段LED時請使用BD83732HFP-M、連接3段LED時請使用BD83733HFP-M。 A Product Change Notice (PCN) is scheduled for this product.
While there will be no changes to electrical characteristics, certain specifications will be updated.
