RESTART OF POWER-ON SEQUENCING
Once a Force Shutdown or Power-off operation has
completed, the SMS66 can restart the Power-on
sequencing. The device can be programmed to
automatically restart after a Force Shutdown provided
the PWR_ON/OFF pin remains in the active state or
the I
2
C Power-on command remains in the command
register. If this option is not selected, the SMS66
requires toggling of the PWR_ON/OFF pin or toggling
of the I
2
C commands by issuing a Power-off command
and then reissuing the Power-on command in order to
restart Power-on sequencing. In either scenario, the
FS pin will prevent the SMS66 from restarting Power-
on sequencing. In addition, the device can be
programmed to check that VDD and the 12VIN are
within their programmed voltage thresholds before
restarting Power-on sequencing.
