DESCRIPTION
1 = FAULT2 is a digital output dependent on MON9*
1 = FAULT2 is a digital output dependent on MON10*
1 = FAULT2 is a digital output dependent on MON11*
1 = FAULT2 is a digital output dependent on MON12*
1 = FAULT2 is a digital output that depends on the overvoltage thresholds at the input
selected by r17h and r18h[3:0]
1 = FAULT2 is a digital output that depends on the undervoltage thresholds at the
input selected by r17h and 18h[3:0]
1 = FAULT2 is a digital output that depends on the early warning thresholds at the
input selected by r17h and r18h[3:0]
0 = FAULT2 is an active-low digital output
1 = FAULT2 is an active-high digital output
Fault-On Power-Up ( FAULTPU )
GPIO6 indicates a fault during power-up or power-
down when configured as a “fault-on power-up” output.
Under these conditions, all EN_OUT_ voltages are
pulled low and fault data is saved to nonvolatile
EEPROM. See the Faults section.
MARGIN
GPIO6 is configurable as an active-low MARGIN input.
Drive MARGIN low before varying system voltages above
or below the thresholds to avoid signaling an error. Drive
MARGIN high for normal operation.
When MARGIN is pulled low or r4Dh[1] is a ‘1,’ the mar-
gin function is enabled. FAULT1 , FAULT2 , Any_Fault,
and RESET are latched in their current state. Threshold
violations will be ignored, and faults will not be logged.
Manual Reset ( MR )
GPIO4 is configurable to act as an active-low manual
reset input, MR . Drive MR low to assert RESET . RESET
remains low for the selected reset timeout period after
MR transitions from low to high. See the RESET section
for more information on selecting a reset timeout period.
Watchdog Input (WDI) and Output (WDO)
Set r1Eh[1:0] and r1Dh[7] to ‘110’ to configure GPIO6 as
WDO. Set r1Dh[6:4] to ‘111’ to configure GPIO5 as WDI.
WDO is an open-drain active-low output. See the
Watchdog Timer section for more information about the
operation of the watchdog timer.
Programmable Outputs
(EN_OUT1–EN_OUT12)
The MAX16047 includes twelve programmable outputs,
and the MAX16049 includes eight programmable out-
puts. These outputs are capable of connecting to either
the enable (EN) inputs of a DC-DC or LDO power supply
or to the gates of series-pass MOSFETs for closed-loop
tracking mode, or for charge-pump mode. Selectable
output configurations include: active-low or active-high,
open-drain or push-pull. EN_OUT1–EN_OUT4 are also
configurable for closed-loop tracking, and EN_OUT1–
EN_OUT6 can act as charge-pump outputs with no
closed-loop tracking. Use the registers r1Fh to r22h to
configure outputs. See Table 8 for detailed information
on configuring EN_OUT1–EN_OUT12.
