Overview
NCV7680 Linear Current Regulator and Controller for Automotive LED Rear Combination Lamps The NCV7680 consists of eight linear programmable constant current sources.
The part is designed for use in the regulation and control of LED based Rear Combination Lamps for automotive applications.
System design with the NCV7680 allows for two brightness levels, one for stop and one for tail illumination, or optional PWM control can also be implemented.
Discrete LED brightness levels are easily programmed (stop current value, tail duty cycle value) optional external ballast FET allows for power distribution on designs requiring high currents.
Set back power limit reduces the drive current during overvoltage conditions.
This is most useful for low current applications when no external FET is used.
Features • Constant Current Outputs for LED String Drive • LED Drive Current up to 75 mA per Channel • Open LED String Diagnostic with Open−Drain Output • Slew Rate Control Eliminates EMI Concerns • Lo...
