Cross-Coupled LEDs
cross-coupled configuration connected to all the outputs of
the NCV7680 in parallel. This allows the user to maintain
illumination of all the remaining LEDs when one fails due
to an open circuit (the most common form of LED failure).
Comparatively, the standard setup shown in Figure 4 will
result in a full string turning off when one LED is open. Be
aware as LEDs fail as open circuits in the cross-coupled
arrangement will cause the row of LEDs to run at a higher
current level affected by the smaller number of LEDs in that
row.
The setup in Figure 24 shows the LEDs set up in a
