ROHM Semiconductor's LED drivers offer exceptional performance solutions for passenger compartment and forward illumination applications. ROHM has expanded its range of highly integrated LED Driver ICs to provide designers 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.
The basic operating requirement for an LED driver is to supply a constant current to LEDs in order to produce consistent lighting. Unlike other market segments, automotive applications have several stringent guidelines in regards to:
• Temperature and humidity range
• Voltage range
• Ability to withstand harsh chemicals
• Electromagnetic interference and
electromagnetic compatibility (EMI)
• Protection circuitry
