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 options. These include 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
- Protection circuitry
