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 register r1Dh[7] to ‘110’ to configure
GPIO6 as WDO. Set r1Dh[6:4] to ‘111’ to configure
Table 9. EN_OUT1–EN_OUT12 Configuration
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 MAX16046 includes twelve programmable outputs,
and the MAX16048 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 out-
put 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.
