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.
OT_INT
D[0]
Overtemperature Interrupt
Reserved
0 = Die Temp < 160°C.
1 = Fault: Die Temp > 160°C.
Set if a fault occurs as a result of the
MIC2593’s die temperature exceeding
160°C.
Undefined.

To reset the OT_INT and UV_INT fault bits, a logical 1 must be written back to these bits.
