General Purpose Input 0, Slot A
State of GPIA pin
INTMSK
Interrupt Mask
0 = /INT generation is enabled
1 = /INT generation is disabled
The MIC2593 does not participate in the SMBus Alert
Response Address (ARA) protocol.
UV_INT
Undervoltage Interrupt
0 = No UVLO fault
1 = UVLO fault
Set whenever a circuit breaker fault condition occurs as
a result of an undervoltage lockout condition on one of
the main supply inputs. This bit is only set if a UVLO
condition occurs while the ON[A/B] pin is asserted or
the MAIN[A/B] control bits are set.
OV_INT
Overtemperature Interrupt
0 = Die Temp < 160癈
1 = Fault: Die Temp > 160癈
Set if a fault occurs as a result of theMIC2593s die
temperature exceeding160癈.
