OPERATION
Indicates State of FET
1 = FET On, 0 = FET Off
State of the GPIO Pin
1 = GPIO High, 0 = GPIO Low
Indicates Potential FET Short if Current Sense Voltage Exceeds 2mV While FET is Off
1 = FET is Shorted, 0 = FET is Not Shorted
Indicates if a Board is Present When BD_PRST is Low
1 = BD_PRST Pin Low, 0 = BD_PRST Pin High
Indicates Power is Bad When FB is Low
1 = FB Low, 0 = FB High
Indicates Overcurrent Condition During Cool Down Cycle
1 = Overcurrent, 0 = Not Overcurrent
Indicates Input Undervoltage When UV is Low
1 = UV Low, 0 = UV High
Indicates Input Overvoltage When OV is High
1 = OV High, 0 = OV Low
