S1F71100 can control circuit operations according to
external signal control. When the POFFX pin is con-
nected to the V

SS

 level, all circuits stop their operations

and their powers are turned off. The current consump-
tion at the power off state is less than 1

µ

A. When the

power is off, the SWO pin is at the V

DD

 level and turns

off the voltage transistor. The voltage at the SSCAP pin

Note :Any operation under conditions exceeding the above absolute maximum ratings may result in a malfunc-

tion or a permanent destruction.   When even an item is more than the rating, a temporary normal operation
is possible but with remarkably low reliability.   So, be sure to keep all items below the ratings.

comes to the V

SS

 level, and the output voltage is con-

trolled with the soft start circuit after the power off state
is released.   In the operating state, set the POFFX pin to
the V

DD

 level to operate it. The POFFX pin cannot be

operated in a open state. When the power off function is
not used, connect the POFFX pin to the V

DD

 pin.
