Shorted Load Recovery
Figure 19 is a continuation of Figure 18. IN X is high
when the auto ? retry timer ends. GAT X goes high and the
blanking and filter timers are started. The fault is removed
before the blanking timer ends, and DRN X starts to fall. As
DRN X passes through the V OL threshold at “A”, the STAB
flag is set. DRN X continues to fall and settles below the
FLTREF threshold.
An SPI frame is sent during the blanking time and returns
data indicating a “shorted load” fault. Although the fault is
removed, updates to the fault latches are suppressed while
a blanking or filter timer is active. The same fault is
captured again and FLTB is set when CSB goes high. At
“B” the blanking time ends and the channel’s fault bits will
indicate “no fault” but because the latched data has not yet
been read, the data remains unchanged.
The SPI frame sent after the blanking time ends returns
a “shorted load” fault because the previous frame occurred
during the blanking time. Since the channel’s fault bits
indicate “no fault”, FLTB is reset and the fault latch is
updated at “C” when CSB goes high. If another SPI frame
is sent before “D”, the returned data will indicate “no
fault”.
The channel is commanded off at “D”. GAT X goes low
and the timers are started. DRN X starts to rise and the STAB
flag is reset as DRN X passes through the V OL threshold.
The SPI frame sent at “E” returns data indicating “no
fault”.
