NCV7681 Datasheet | onsemi

100 m A Linear Current Regulator and Controller for Automotive LED Lighting The NCV7681 consists of eight linear programmable constant current sources. The part is designed for use in the regulation and control of LED based Rear bination Lamps and blinking functions for automotive applications. System design with the NCV7681 allows for two programmed levels for stop (100% Duty Cycle) and tail illumination (programmable Duty Cycle), or an optional external PWM control can be implemented. LED brightness levels are easily programmed (stop is programmed to the absolute current value, tail is programmed to the duty cycle) with two external resistors. The use of an 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 power applications when no external FET is used. The device is available in a SOIC- 16 WB package with exposed...
