sequence delay is then counted before moving to the
next slot.
Slot 0 does not monitor any MON_ input and does not
control any EN_OUT_. Slot 0 waits for the Software
Enable bit r73h[0] to be a logic-high and for the voltage
on EN to rise above 1.4V before initiating the power-up
sequence and counting its own sequence delay.
Any MON_ input that suffers a fault that occurs during
power-up sequencing causes all the EN_OUT_s to turn
off and the sequencer to shut down regardless of the
state of the critical fault enables (see the Faults section
for more information). If a MON_ input is less critical to
system operation, it can be configured as “monitoring
only” (see Table 6) for either the primary or secondary
sequence. Monitoring for MON_ inputs assigned as
“monitoring only” begins after sequencing is complete
for that group, and can trigger a critical fault only if
specifically configured to do so using the critical fault
enables.
Power-Up
On power-up, when EN is high and the Software Enable
bit is 1, the MAX16065/MAX16066 begin sequencing
with Slot 0. After the sequencing delay for Slot 0 expires,
the sequencer advances to Slot 1, and all EN_OUT_s
assigned to the slot assert. All MON_ inputs assigned to
Slot 1 are monitored and when the voltage rises above the
UV fault threshold, the sequence delay counter is started.

When the t FAULT counter expires before all MON_ inputs
assigned to the slot are above the fault UV threshold,
a fault asserts. EN_OUT_ outputs are disabled and the
MAX16065/MAX16066 return to the power-off state.
When the sequence delay expires, the MAX16065/
MAX16066 proceed to the next slot.
After the voltages on all MON_ inputs assigned to the
last slot exceed the UV fault threshold and the slot delay
expires, the MAX16065/MAX16066 start the reset time-
out counter. After the reset timeout, RESET deasserts.
r75h[4:1] sets the t FAULT delay. See Table 7 for details.
Power-Down
Power-down starts when EN is pulled low or the Software
Enable bit is set to ‘0.’ Power down EN_OUT_s simul-
taneously or in reverse-sequence mode by setting the
Reverse Sequence bit (r75h[0]) appropriately.
Reverse-Sequence Mode
When the MAX16065/MAX16066 are fully powered up
(including secondary sequence group, if enabled) and
EN or the Software Enable bit is set to ‘0’, the EN_OUT_s
assigned to Slot 12 deassert, the MAX16065/MAX16066
wait for the Slot 12 sequence delay and then proceed to
the previous slot (Slot 11), and so on until the EN_OUT_s
assigned to Slot 1 turn off. When simultaneous power-
down is selected (r75h[0] set to ‘0’), all EN_OUT_s turn
off at the same time.
