Introduction
The NCV78343 is a single−chip pixel controller with embedded
switches to control individual LEDs in a series LED string, designed
for automotive dynamic lighting applications and in particular for high
current LEDs. In order to create a pixel lighting solution, the LEDs
need to be powered by current sources such as NCV78763 or
NCV78723. The NCV78343 pixel controller devices receive the pixel
control parameters from the pixel light ECU which translates the
required light pattern or light image into individual pixel dimming
data.
One pixel controller device can control up−to 12 pixels of 1× or 2×
1.4 A LEDs per pixel. The maximum LED string voltage has to be
limited to 60 V.
When more than 12 pixels are to be controlled, multiple pixel
controllers can be combined in a single system.

Package
Shipping
The NCV78343 uses two communication interfaces for connection
with a microcontroller. A universal asynchronous receiver transmitter
(UART), which supports the use of CAN transceiver and multipoint
low voltage differential signaling (M−LVDS) for either local
connection or connection with the MCU.
