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.
Configure GPIO2 and GPIO3 as margin-up
(MARGINUP) and margin-down (MARGINDN) inputs,
respectively, for margining functionality. Pull
MARGINUP low and pull MARGINDN high to select
DACOUT_ voltage values set in registers r66h to r71h.
Pull MARGINDN low and pull MARGINUP high to select

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
DACOUT registers r00h to r0Bh
MARGINDN registers r72h to r7Dh
MARGINUP registers r66h to r71h
DACOUT registers r00h to r0Bh
DACOUT REGISTER USED
DACOUT_ values set in registers r72h to r7Dh. Pull
both MARGINUP and MARGINDN high or low to select
DACOUT_ values set in registers r00h to r0Bh. See the
Voltage Margining section for more information on set-
ting DACOUT_ outputs for margining.
Margin-up and margin-down functionality is controlled
by GPIO2 and GPIO3 when configured for margining
(see Table 8). When MARGINUP or MARGINDN are
asserted, the DAC output switches are automatically
closed and the margin function is enabled. Writing to
the DAC-enabled registers (r1Ch and r1Dh) is not
required to close the DAC switches. See the MARGIN
section for an explanation of the margin function.
