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.
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.
Set r1Eh[1:0] and register r1Dh[7] to ‘110’ to configure
GPIO6 as WDO. Set r1Dh[6:4] to ‘111’ to configure

EN_OUT1 Configuration:
000 = EN_OUT1 is an open-drain active-low output
001 = EN_OUT1 is an open-drain active-high output
010 = EN_OUT1 is a push-pull active-low output
011 = EN_OUT1 is a push-pull active-high output
100 = EN_OUT1 is used in closed-loop tracking
101 = EN_OUT1 is configured with a charge-pump output (MON1 + 5V) capable of
driving an external n-channel MOSFET

111 = Reserved
EN_OUT2 Configuration:
000 = EN_OUT2 is an open-drain active-low output
001 = EN_OUT2 is an open-drain active-high output
010 = EN_OUT2 is a push-pull active-low output
011 = EN_OUT2 is a push-pull active-high output

EN_OUT3 Configuration (LSBs):
000 = EN_OUT3 is an open-drain active-low output
001 = EN_OUT3 is an open-drain active-high output
010 = EN_OUT3 is a push-pull active-low output
011 = EN_OUT3 is a push-pull active-high output
100 = EN_OUT3 is used in closed-loop tracking
101 = EN_OUT3 is configured with a charge-pump output (MON3 + 5V) capable of
driving an external n-channel MOSFET

MARGIN
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.
The MAX16046A includes twelve programmable out-
puts, and the MAX16048A includes eight programma-
ble outputs. 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 9 for detailed information on configuring
EN_OUT1–EN_OUT12.
