The MAX5930A/MAX5931A/MAX5931B turn off the cor-
responding channel if any of the above conditions are
not met. During a fault condition on a given channel
only, the affected channel is disabled. After a fault-
latched shutdown, recycle the corresponding ON_
inputs to unlatch and restart only the corresponding
channel.
