1-1.
When the power supply voltage (V
DD
) is higher than the release voltage (
+
V
DET
), the Nch transistor is
OFF and the Pch transistor is ON to provide V
DD
(high) at the output. Since the Nch transistor N1 in
Figure 15
is OFF, the comparator input voltage is

When the V
DD
goes below
+
V
DET
, the output provides the V
DD
level, as long as the V
DD
remains above
the detection voltage
V
DET
. When the V
DD
falls below
V
DET
(point A in
Figure 16
), the Nch transistor
becomes ON, the Pch transistor becomes OFF, and the V
SS
level appears at the output. At this time
the Nch transistor N1 in
Figure 15
becomes ON, the comparator input voltage is changed to
V
R
+
1-3.
When the V
DD
falls below the minimum operating voltage, the output becomes undefined, or goes to the
V
DD
when the output is pulled up to the V
DD
.

The V
SS
level appears when the V
DD
rises above the minimum operating voltage. The V
SS
level still
appears even when the V
DD
surpasses
V
DET
, as long as it does not exceed the release voltage

When the V

rises above

DET
(point B in

transistor becomes ON to provide V
