FAULTA
FAULT Status, Slot A
1 = /FAULTA pin asserted
(/FAULTA pin is LOW)
0 = /FAULTA pin de-asserted
(/FAULTA pin is HIGH)
See Notes 1 and 2
MAINA
MAIN Enable Status, Slot A
Represents the actual state (on/off) of the four Main
Power outputs for Slot A (+12V, 12V, +5V and +3.3V)
1 = Main Power ON
0 = Main Power OFF
VAUXA
VAUX Enable Status, Slot A
Represents the actual state (on/off) of the Auxiliary
Power output for Slot A
1 = AUX Power ON
0 = Main Power OFF
VAUXAF
Overcurrent Fault: VAUXA supply A
1 = Fault, 0 = No fault
12MVAF
Overcurrent Fault: 12V supply A
1 = Fault, 0 = No fault
12VAF
Overcurrent Fault: +12V supply A
1 = Fault, 0 = No fault
5VAF
Overcurrent Fault: 5V supply A
1 = Fault, 0 = No fault
3VAF
Overcurrent Fault: 3V supply A
1 = Fault, 0 = No fault

The power-up default value is 00

. Both slots are disabled upon power-up, i.e., all supply outputs are off. In response to
anovercurrent fault condition, writing a logical 1 back into the active (or set) bit position will clear the bit and de-assert /INT.
Thestatus of the /FAULTA pin is not affected by reading the Status Register or by clearing active status bits.
Note 1.
If FAULTA has been set by an overcurrent condition on one or more of the MAIN outputs, the ONA input must go LOW to reset FAULTA.
If FAULTA has been set by a VAUXA overcurrent event, the AUXENA input must go LOW to reset FAULTA.
If an overcurrent has occurred on both a MAIN output and the VAUX output of slot A, both ONA and AUXENA of the slot must go low to
reset FAULTA.
Note 2.
Neither the FAULTA bit nor the /FAULTA pin is active when the MIC2593 power paths are controlled by the System Management
Interface. When using SMI power path control, AUXENA and ONA pins for that slot must be tied to GND.
