Enhanced 100 m A Linear MARKING DIAGRAM Current Regulator and Controller for Automotive Sequenced LED Lighting SSOP24 NB EP CASE 940AP NCV7683G AWLYYWW NOTE: This marking style is specific to Case 940AP NCV7683 = Specific Device Code The NCV7683 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 = Assembly Location WL = Wafer Lot YY = Year WW = Work Week = Pb- Free Package NCV7683 allows for two programmed levels for stop (100% Duty Cycle) and tail illumination (programmable Duty Cycle), or an MARKING DIAGRAM 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 SSOP24 NB EP CASE 940AQ NCV7683 FAWLYWW G back power limit reduces the drive current during overvoltage conditions. This is most useful for low power applications when no external FET is used. Sequencing functionality is activated, controlled, and programmed by individual pins. In addition to programming of the sequence interval, the device can sequence 8 individual output channels, 4 pairs of output channels, 2 quad output channels, or all 8 at once (for multi IC use at high currents).
