ROHM recently announced the availability of 4ch linear LED driver ICs with built-in MOSFET ideal for LED rear lamps (turn/stop), fog lamps and turn signals for automotive use.
In recent years the adoption of automotive-grade LED lamps is advancing from the viewpoint of power savings and design flexibility, while the number of lamps and brightness levels are increasing significantly. In the Asian region for example, where 2-wheeled vehicles are the main means of transportation for many, a number of vehicle manufacturers are demanding simpler circuit configurations for driving standard rear and license plate lamps in order to reduce costs and shorten development time. However, until now thermal design issues have made it difficult for LED drivers that power LEDs to meet all of the various requirements in terms of number of lamps, brightness, safety, and costs.
In response, by analyzing the demands in India, the largest market for 2-wheeled vehicles, ROHM was able to develop LED drivers that solve these issues utilizing 2 new technologies (more info).
