Rohm Semiconductor LED Drivers

ROHM Semiconductor LED Drivers combine LED driver Integrated Circuits (IC) required for LED lighting control and compact high-reliability LEDs for automotive lighting solutions. LED drivers achieve smaller and thinner light sources, have a longer life, reduced power consumption, high reliability, and reduced costs compared to traditional bulbs. These LED driver ICs can detect errors such as LED open/short failures and provide external notification that helps detect unsafe conditions such as LED brightness drops due to unstable operation. The LED drivers are suitable for use in various applications including camera flash, consumer electronics, displays, exterior vehicle lamps, and in-vehicle illumination.
