LED Driver Handles Headlamp Cluster Functions

Suitable for high-beam, low-beam, and daytime running light circuits, the Model BD8381EFV-M high-brightness LED driver provides stable operation over an input voltage from 5V to 30V and removes constraints on the number of LEDs in a series connection. Integrated protection monitors voltage, current, and temperature as well as LED open and short circuits. Other features include a PWM controller so dimming functions can be implemented with a simple external CR circuit. Pricing is $8 each in small OEM quantities. ROHM SEMICONDUCTOR, San Diego, CA.
