Happy viewing!!!
The usage of light-emitting diodes (LEDs) in automotive applications is increasing for the same reasons that LED lighting is penetrating non-automotive sectors. LEDs are more efficient and smaller in size, have a substantially longer life, allow considerably greater design freedom for improved aesthetics, and more.
While the basic operating requirement for an LED driver is to supply a constant current to LEDs in order to produce consistent lighting, automotive applications -unlike other market segments- have more stringent guidelines with regards to temperature and humidity range, voltage, ability to withstand harsh chemicals, electromagnetic interference and electromagnetic compatibility (EMI) as well as protection circuitry.
This work describes the different options designers have to integrate a LED driver solution. Rohm has expanded its range of highly integrated LED driver ICs to provide a variety of design options with integrated or externally switched outputs, parallel/series control and extensive protection and fault detection functions in small surface mount packages.
