The MAX5927A/MAX5929A–MAX5929D turn off all
channels if any of the above conditions are not met.
After a fault-latched shutdown, cycle any of the ON_
inputs to unlatch and restart all channels.
Leave MODE floating to enter power-sequencing
mode. While in power-sequencing mode, the
MAX5927A/MAX5929A–MAX5929D turn on and off
