OPERATION
Indicates Potential FET Short was Detected When Measured Current Sense Voltage Exceeded 2mV
While FET was Off
1 = FET was Shorted, 0 = FET is Good
Indicates that a Board was Inserted or Extracted When BD_PRST Changed State
1 = BD_PRST Changed State, 0 = BD_PRST Unchanged
Indicates Power was Bad When FB Went Low
1 = FB was Low, 0 = FB was High
1 = Overcurrent Fault Occurred, 0 = No Overcurrent Faults
Indicates Input Undervoltage Fault Occurred When UV Went Low
1 = UV was Low, 0 = UV was High
Indicates Input Overvoltage Fault Occurred When OV Went High
1 = OV was High, 0 = OV was Low
