NCV7430/D
NCV7430
Automotive LIN RGB LED
Driver
The NCV7430 is a single−chip RGB driver intended for dedicated
multicolor LED applications. The RGB LED driver contains a LIN
interface (slave) for parametric programming of LED color and intensity.
The device receives instructions through the LIN bus and
subsequently drives the LEDs independently.
The NCV7430 acts as a slave on the LIN bus and the master can
request specific status information (parameter values and error flags).
The LIN address of the NCV7430 can be programmed in the internal
memory of the device.
The NCV7430 is fully compatible with automotive requirements.
