Monitoring Inputs While Sequencing
An enabled MON_ input can be assigned to a slot
ranging from Slot 1 to Slot 6. EN_OUT_s are always
asserted at the beginning of a slot. The supply voltages
connected to the MON_ inputs must exceed the under-
voltage threshold before the programmed fault timeout
period expires, otherwise, a fault condition occurs. Once
a MON_ input crosses the undervoltage threshold, the
monitoring for overvoltage begins. The undervoltage
and overvoltage threshold checking cannot be disabled
during power-up and power-down. See Tables 5 and
6 for the MON_ slot assignment bits. The programmed
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 1.24V (typ) before initiating the pow-
er-up sequence and counting its own sequence delay.
Any MON_ input that suffers a fault 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). If a
MON_ input is less critical to system operation, it can
be configured as “monitoring only” (see Table 6a) for
sequencing. Monitoring for MON_ inputs assigned as
“monitoring only” begins after sequencing is complete,
and can trigger a critical fault only if specifically config-
ured to do so using the critical fault enables.
