Multiple Drivers Operation
For large LCD panels where more than 6channels of LEDs
are needed, multiple ISL97671s with each driver having
its own supporting components can be controlled
together with the common SMBus/I
ISL97671 does not have extra pins strappable slave
address feature, but a separate EN signal can be applied
to each driver for asynchronous operation. A trade-off of
such scheme is that an exact faulty channel cannot be
identified since both controllers have the same I
address.
