Automotive LED Lighting Drivers and Solutions
LEDs can be used in all parts of automotive lighting, from headlights to fog lights, instrument backlighting to mirror lighting, taillight lighting, interior lighting, etc. ON Semiconductor provides a series of standard lighting simulation products such as NCV3065 and discrete devices such as NSI45 series, as well as a series of products such as ASSP obtained from the acquisition of AMIS, to provide professional automotive-grade lighting solutions for different lighting subsystems.
With the development of the automobile industry, more and more advanced lighting technology is being used more and more in automobiles. Among them, LED lighting has the incomparable advantages of halogen lamps and xenon lamps, such as long life, fast response time, energy saving and environmental protection, etc., which has accelerated the pace of mass adoption in automotive lighting.
In this regard, ON Semiconductor provides a broad lineup of products for automotive headlamp lighting applications, from general bulb driver solutions to stepper drivers, LED drivers and xenon lamp drivers, etc., and continues to focus on automotive headlamps, dashboard backlights, interior lighting, Automotive lighting applications such as door lighting and taillights offer a wide range of solutions including standard and custom products, especially in headlight adjustment, xenon lamp driver ASICs for deflection and stepper drivers that have become the de facto standard in the market.
Various types of product features and overall solutions
ON Semiconductor linear regulators are aimed at low-circuit applications, such as 20mA LEDs. Its total power consumption is relatively low, it can work in an environment of 85 degrees, and the system integration is relatively low, such as NSI45 series CCR or NUD series. meet such requirements;
For the switching regulator, its characteristic is that the LED power will be relatively high, which can reach about 700mA, which belongs to the middle and high total power consumption, and can work in an environment as high as 125 degrees. Its system integration is also relatively low, and can be used with NCV3056/66 series realize its control;
For the lighting management integrated chip, its power is also relatively large, and the ambient temperature can also reach 125 degrees. It is a complete and independent subsystem, so the integration level will be relatively high. NCV78663 and NCV7680 are used for this application.
