NXP launched the first car driver chip LED

NXP semiconductors in November 15 announced, according to LED car headlights and taillights, launched a complete automotive grade based on the technology of a type of highly flexible driver chip solutions. ASL1010NTK and ASL1010PHN using 8/16 pin package, is the industry's first integrated many core features of automotive LED driver chip. At present, LED has been used for general purpose solid state lighting (SSL) application of the driver chip, not only complex, expensive, and the lack of automotive applications required a variety of core functions. With the increasing popularity of solid state lighting in the automotive industry, lighting control device manufacturers and LED vendors need to be more powerful, more efficient solutions, so that OEM providers can give full play to the advantages of LED energy saving. Because compared with incandescent lamps, LED can save about 50% of fuel consumption and power consumption in some applications (UMTRI, 2008). ASL1010NTK/ASL1010PHN driver IC integrates the core functions of automotive LED lights, is a compact integrated solution, and no additional components. For the LED module design, is conducive to reduce costs, enhance the aesthetic, improve reliability. The solution system of NXP has very high flexibility, not by car platform, configuration, the output voltage and the limit to the number of LED. The product can be used for different vehicle platforms. The LED driver chip NXP adopts automatic buck / boost topology, using the standard car battery voltage can drive up to 20 LED lamps; the output voltage is extremely flexible, ranging from 6V to 60V, in support of the market on the various types of LED. The core function of the chip has been integrated automobile LED drive, can reduce the volume, the reference design increases the design flexibility, and can easily cope with different configuration and the number of LED, without the need to re design the PCB board. Integrated design from different platforms redundant function and external harrier micro controller. In addition, ASL1010NTK/ASL1010PHN driver chip ABCD9 technology node based on NXP - this is made to promote analog mixed signal integrated automotive technology platform. The other main function of the NXP LED driver chip includes: 1, temperature feedback function, temperature and performance of can control LED 2, fault detection function, can provide feedback when the failure occurred in the LED 3, LED 4, short circuit protection function eliminates LED ripple current, without external components, the external current 5 Selection and PWM programming function 6, adjustable LED internal PWM function, to allow the same LED lights at the same time as daytime running lights and parking lamps 7, LED undervoltage and overvoltage protection function 8, small package NXP ASL1010NTK/ASL1010PHN car LED driver chip will provide samples at the end of November, and will be on display in Germany in 2010 Munich electronics show.
