12-Channel/8-Channel EEPROM-Programmable
System Managers with Nonvolatile Fault Registers
After any MON_ inputs assigned to Slot 12 exceed their
undervoltage thresholds, the reset timeouts begin. When
the reset timeout completes, RESET deasserts. The reset
timeout period is set in r19h[6:4] (see Table 27).
Power-down starts when EN is pulled low or the
Software Enable bit is set to ‘1.’ RESET asserts as soon
as power-down begins regardless of the reset output

Power-Down
dependencies. Power down EN_OUT_s simultaneously
or in reverse sequence mode by setting the Reverse
Sequence bit (r54h[4]) appropriately. In reverse
sequence mode (r54h[4] set to ‘1’), the EN_OUT_s
assigned to Slot 11 deassert, the MAX16046/
MAX16048 wait for the Slot 11 sequence delay and
then proceed to Slot 10, and so on until the EN_OUT_s
assigned to Slot 0 turn off. When simultaneous power-
down is selected (r54h[4] set to ‘0’), all EN_OUT_s turn
off at the same time.
