Absolute Maximum Ratings - Epson Power Supply IC S1F70000 Technical Manual

Power Off Function
S1F71100 can control circuit operations according to
external signal control. When the POFFX pin is con-
nected to the V level, all circuits stop their operations
SS
and their powers are turned off. The current consump-
tion at the power off state is less than 1 A. When the
power is off, the SWO pin is at the V
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.
