The MAX5927A/MAX5929AMAX5929D 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.
Power-Sequencing Mode
Leave MODE floating to enter power-sequencing
mode. While in power-sequencing mode, the
MAX5927A/MAX5929AMAX5929D turn on and off
each channel depending on the state of the corre-
sponding V
ON_
. To turn on a given channel:
" At least one V
IN_
must exceed V
UVLO
(2.45V) for the
UVLO to startup delay (37.5ms).
" All V
IN_
must exceed V
PWRRDY
(0.95V).
" The corresponding V
ON_
must exceed V
ON,TH
(0.875V).
" No faults can be present on any channel.
