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

2C Power-on command remains in the command

requires toggling of the PWR_ON/OFF pin or toggling

of the I

2C 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.
