The fault control circuitry provides two forms of power
shutdown:
Complete turn-off of all four output power stages.
Clamping the phase shift command to zero.
Complete turn-off is ordered for an over-current fault or
a low supply voltage. When the SOFTSTART pin
reaches its low threshold, switching is allowed to pro-
ceed while the phase-shift is advanced from zero to its
nominal
value
with
the
SOFT-START capacitor.

the
The fault logic insures that a continuous fault will insti-
tute a low frequency “hiccup” retry cycle by forcing the
SOFT-START capacitor to charge through its full cycle
between each restart attempt.
