Power Off Function
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.
