Short to GND/Open Load
Figure 20 illustrates turn ? off with an open or high
resistance load when some capacitance is present at DRN X .
In the case of an open load, DRN X rises and settles to V CTR .
In the case of a high resistance load, DRN X may continue
to rise and may eventually settle to V LOAD .
The channel is commanded off. GAT X goes low and the
timers are started. DRN X starts to rise and is below the V SG
threshold when the blanking time ends at “A”. A short to
GND fault is detected and captured by the fault latch, and
the FLTB flag is set.
DRN X continues to rise and as it passes through the V SG
threshold at “B”, the filter timer is triggered. At the end of
the filter time, the channel’s fault bits will indicate an
“open load” but because the latched data has not yet been
read, the data remains unchanged.
An SPI frame sent shortly after “B” returns data
indicating “short to GND” and the fault latch is updated at
“C” when CSB goes high. The next three frames sent after
“C” return data indicating an “open load”.
The STAB flag is reset at “D” as DRN X passes through
the V OL threshold. Note that the filter timer is not triggered
as DRN X passes from a fault state to a good state. The
channel’s fault bits will indicate “no fault” but because the
latched data has not yet been read, the data remains
unchanged.
The fault latch is updated at “E” when CSB goes high and
the FLTB flag remains reset. The next SPI frame sent
returns data indicating “no fault”.
