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 Combination 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 pad.
