Always read as zero
Always read as zero
State of GPIB pin
State of GPIA pin
0 = /INT generation is
enabled
1 = /INT generation is
disabled.
The MIC2590B does
not participate in the
SMBus Alert
Response Address
(ARA) Protocol.
Set whenever a
circuit Interrupt
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 one or both of
the ON[A/B] pins are
asserted or the
MAIN[A/B] enable
control bits are set.
Set whenever a
circuit breaker fault
occurs as a result of
an overtemperature
condition exceeding
160°C shutting both
channels off.
Read Undefined
Power-Up Default Value:
0000 0000b = 00h
Command Byte (R/W):
0000 0110b = 06h
To reset the OT_INT and UV_INT fault bits a logical
1must be written back to these bits.
