Enable
To initiate sequencing/tracking and enable monitoring,
the voltage at EN must be above 0.525V and the
Software Enable
bit in r4Dh[0] must be set to ‘0.’ To
power down and disable monitoring, either pull EN
below 0.5V or set the
Software Enable
bit to ‘1.’ See
Table 1 for the software enable bit configurations.
Connect EN to ABP if not used.
If a fault condition occurs during the power-up cycle,
the EN_OUT_ outputs are powered down immediately,
independent of the state of EN. If operating in latch-on
fault mode, toggle EN or toggle the
Software Enable
bit
to clear the latch condition and restart the device once
the fault condition has been removed.

bit
0 = Enabled. EN must also be high to begin sequencing.
1 = Disabled (factory default)

Margin bit
1 = Margin functionality is enabled
0 = Margin disabled
2
Early Warning Selection bit
0 = Early warning thresholds are undervoltage thresholds
1 = Early warning thresholds are overvoltage thresholds

0 = Watchdog timer is in dependent mode
1 = Watchdog timer is in independent mode

Voltage Monitoring
The MAX16046/MAX16048 feature an internal 10-bit
ADC that monitors the MON_ voltage inputs. An internal
multiplexer cycles through each of the twelve inputs,
taking 100μs (typ) for a complete monitoring cycle.
Each acquisition takes approximately 8.3μs. At each
multiplexer stop, the 10-bit ADC converts the analog
input to a digital result and stores the result in a regis-
ter. ADC conversion results are stored in registers r00h
to r17h in the extended page. Use the I
2
C or JTAG seri-
al interface to read ADC conversion results. See the
I
2
C/SMBus-Compatible Serial Interface or the JTAG
Serial Interface section for more information on access-
ing the extended page.
The MAX16046 provides twelve inputs, MON1–MON12,
for voltage monitoring. The MAX16048 provides eight
inputs, MON1–MON8, for voltage monitoring. Each
input voltage range is programmable in registers r0Fh
to r11h (see Table 2). When MON_ configuration
registers are set to ‘11,’ MON_ voltages are not moni-
tored or converted, and the multiplexer does not stop at
these inputs, decreasing the total cycle time. These
inputs cannot be configured to trigger fault conditions.
The three programmable thresholds for each monitored
voltage include an overvoltage, an undervoltage, and
an early warning threshold that can be set in r4Dh[2] to
be either an undervoltage or overvoltage threshold. See
the Faults section for more information on setting over-
voltage and undervoltage thresholds. All voltage
thresholds are 8 bits wide. The 8 MSBs of the 10-bit
ADC conversion result are compared to these overvolt-
age and undervoltage thresholds.
For any undervoltage or overvoltage condition to be
monitored and any faults detected, the MON_ input
must be assigned to a particular sequence order. See
the Sequencing section for more details on assigning
MON_ inputs.
