BD83733HFP-M
车载用 50V 500mA 1ch LED源极驱动器
BD83733HFP-M是50V高耐压LED源极驱动器。恒电流输出可进行PWM调光，适合车载用LED驱动。内置LED开路/短路检测、LED电流降额功能，可实现高可靠性。通过使用已获得专利的PBUS功能，在使用多个本LSI驱动多列LED时，即使当某列LED发生了开路/短路，也可以对全部LED进行统一的OFF控制。输出IOUT端子上连接2段LED时请使用BD83732HFP-M、连接3段LED时请使用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.
