Bits Bit Name Settings Description Reset Access
4 VIN_UV_FAULT Latched register. 0x0 R
0 No undervoltage detected on the UVx pin.
1 An undervoltage was detected on the UVx pin.
[3:1] RESERVED Always reads as 000. 0x0 R
0 PIN_OP_WARN Latched register. 0x0 R
0
No overpower condition on the input supply detected by the power
monitor.
1
An overpower condition on the input supply was detected by the
power monitor.

7 FET_HEALTH_BAD Latched register. 0x0 R
0 FET behavior appears to be as expected.
1 FET behavior suggests that the FET may be shorted.
6 UV_CMP_OUT Live register. 0x0 R
0 Input voltage to UVx pin is above threshold.
1 Input voltage to UVx pin is below threshold.
5 OV_CMP_OUT Live register. 0x0 R
0 Input voltage to OV pin is below threshold.
1 Input voltage to OV pin is above threshold.
4 VAUX_STATUS Latched register. 0x0 R
0 There are no active status bits to be read by STATUS_VAUX.
1 There are one or more active status bits to be read by STATUS_VAUX.
3 HS_INLIM_FAULT Latched register. 0x0 R
0 The ADM1075 has not actively limited the current into the load.
1
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.
[2:1] HS_SHUTDOWN_CAUSE Latched register. 0x0 R
00
The ADM1075 is either enabled and working correctly, or has been
shut down using the OPERATION command.
01
An IOUT_OC_FAULT condition occurred that caused the ADM1075
to shut down.
10
A VIN_UV_FAULT condition occurred that caused the ADM1075 to
shut down.
11
A VIN_OV_FAULT condition occurred that caused the ADM1075 to
shut down.
0 IOUT_WARN2 Latched register. 0x0 R
0
No overcurrent condition on the output supply detected by the
power monitor using the IOUT_WARN2_LIMIT command.
1
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.
