Description
Latched register.
No undervoltage detected on the UVx pin.
An undervoltage was detected on the UVx pin.
Latched register.
No overpower condition on the input supply detected by the power
monitor.
An overpower condition on the input supply was detected by the
power monitor.
Description
Latched register.
FET behavior appears to be as expected.
FET behavior suggests that the FET may be shorted.
Live register.
Input voltage to UVx pin is above threshold.
Input voltage to UVx pin is below threshold.
Live register.
Input voltage to OV pin is below threshold.
Input voltage to OV pin is above threshold.
Latched register.
There are no active status bits to be read by STATUS_VAUX.
There are one or more active status bits to be read by STATUS_VAUX.
Latched register.
The ADM1075 has not actively limited the current into the load.
The ADM1075 has actively limited current into the load. This bit
differs from the IOUT_OC_FAULT bit in that the HS_INLIM bit is set
immediately, whereas the IOUT_OC_FAULT bit is not set unless the
time limit set by the capacitor on the TIMER pin elapses.
Latched register.
The ADM1075 is either enabled and working correctly, or has been
shut down using the OPERATION command.
An IOUT_OC_FAULT condition occurred that caused the ADM1075
to shut down.
A VIN_UV_FAULT condition occurred that caused the ADM1075 to
shut down.
A VIN_OV_FAULT condition occurred that caused the ADM1075 to
shut down.
Latched register.
No overcurrent condition on the output supply detected by the
power monitor using the IOUT_WARN2_LIMIT command.
An undercurrent or overcurrent condition on the output supply was
detected by the power monitor using the IOUT_WARN2_LIMIT
command. The polarity of the threshold condition is set by the
IOUT_WARN2_OC_SELECT bit using the DEVICE_CONFIG command.
