EXTERNAL FAULT TRIP Bit
OVER-VOLTAGE TRIP Bit
UNDER-VOLTAGE Bit
This read-only bit indicates a FAULT has occurred resulting from a logic 1
applied to the FAULTIN pin.
This read-only bit indicates if the voltage at the DC_BUS pin exceeds the
preset value of V
This read-only bit indicates if the voltage at the DC_BUS pin is less than the
present value of V

1 = A logic 1 was applied to the FAULTIN pin and a FAULT timeout is still
0 = A logic 0 is applied to the FAULTIN pin and no FAULT timeout is in
1 = The voltage applied to the DC_BUS pin has exceeded the preset
0 = The voltage applied to the DC_BUS pin is less than the preset value
1 = The voltage applied to the DC_BUS pin is less than the present value
