Description
No overvoltage detected on the OV pin.
An overvoltage was detected on the OV pin.
No overvoltage condition on the input supply detected by the power
monitor.
An overvoltage condition on the input supply was detected by the power
monitor.
No undervoltage condition on the input supply detected by the power
monitor.
An undervoltage condition on the input supply was detected by the
power monitor.
No undervoltage detected on the UV pin.
An undervoltage was detected on the UV pin.
Always reads as 000.
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
FET behavior appears to be as expected.
FET behavior suggests that the FET may be shorted.
Input voltage to UV pin is above threshold.
Input voltage to UV pin is below threshold.
Input voltage to OV pin is below threshold.
Input voltage to OV pin is above threshold.
Always reads as 0.
The ADM1276 has not actively limited the current into the load.
The ADM1276 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.
The ADM1276 is either enabled and working correctly, or has been shut
down using the OPERATION command.
An IOUT_OC_FAULT condition occurred that caused the ADM1276 to shut
down.
A VIN_UV_FAULT condition occurred that caused the ADM1276 to shut down.
A VIN_OV_FAULT condition occurred that caused the ADM1276 to shut down.
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_SELECT
bit using the DEVICE_CONFIG command.
