IOUT_NC_FAULT is set to 1 when a negative current
flow is detected.
Table 12. Fault Response Options
The MFR_FAULT_STATUS command value cannot be
restored by the RESTORE_DEFAULT_ALL command.
This command is read only.
MFR_FAULT_RESPONSE (D9h)
The MFR_FAULT_RESPONSE command specifies the
response to each fault condition supported by the
MAX8688. Each fault has 2 response bits that describe
how the MAX8688 should respond to that particular
fault. It is also used to record the condition under which
a fault occurs.
The STORE_PEAK function is used to store peak values
(MFR_VOUT_PEAK, MFR_IOUT_PEAK, and MFR_TEM-
PERATURE_PEAK) to the EEPROM (if present) on a
fault detection regardless of the status of the EEPROM
Lock Enable bit. Setting the STORE_PEAK bit to 1
enables the store function.

Reserved. Same response as 00 except this
option also stores peak data to EEPROM if
enabled.
Set the corresponding fault bit in the fault status
register, assert FLT , shutdown the POL
(deasserted ENOUT), and restart the POL every
T (μs), where T is set in the MFR_FAULT_RETRY
register. Store peak data to EEPROM if enabled.
Set the corresponding fault bit in the fault status
register, assert FLT , and shutdown the POL.
Store peak data to EEPROM if enabled.
Set the corresponding fault bit in the fault status
register, assert FLT , and continue operation

between restarting the POL if the fault response is to
restart the POL at specified intervals. This command
sets the retry time delay in multiples of 100μs. This
command value is used for all fault responses that
require delay retry.
Delay retry time = MFR_FAULT_RETRY[15:0] x 100μs
The 2 data bytes are in DIRECT format. Valid values are
from 0 to 3.2768s. When MFR_FAULT_RETRY = 00h,
the MAX8688 restarts the POL at the next available time
period.
Table 12 describes how the MAX8688 responds to fault
conditions. If the fault response requires ENOUT to be
deasserted, ENOUT deasserts immediately. Meanwhile
the DAC output ramps down slowly. The fault bit is
cleared according to the Fault Management and
Reporting section.
If ENOUT is deasserted due to a fault condition, the
POL shall remain OFF until instructed to change.
The default MFR_FAULT_RESPONSE value is 00h.
The default MFR_FAULT_RETRY value is 00h.
MFR_SET_ADDRESS (DBh)
The MFR_SET_ADDRESS command is used to change
the MAX8688 slave address. By default the MAX8688
address is set by A3:A1 upon reset according to Table
3. After reset, the slave address can be changed by
the MFR_SET_ADDRESS command. See the MAX8688
Address Assignment section.
This command has 2 data bytes. The slave address is
contained in bits [6:0] of the first data byte. Bit 7 of the
first data byte must be 0.
