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