Seiko Instruments Inc.
Operation
1.
Basic operation : CMOS active low output
(1) When power supply voltage V
DD
is greater than the release voltage +V
DET
, the Nch transistor is OFF and the Pch
transistor ON, causing V
DD
(high) to appear at the output. With the Nch transistor N1 of Figure 9 OFF, the comparator
input voltage is (RB+RC)/(RA+RB+RC)

V
DD
.
(2) When power supply voltage V
DD
goes below +V
DET
, the output maintains the power supply voltage level, as long as V
DD
remains above the detection voltage -V
DET
. When V
DD
does fall below -V
DET
(A in Figure 10), the Nch transistor goes ON,
the Pch transistor goes OFF, and V
SS
appears at the output. With the Nch transistor N 1 of Figure 9 ON, the comparator
input voltage is RB/(RA+RB)
×
V
DD
.
(3) When V
DD
falls below the minimum operating voltage, the output becomes undefined. However, output will revert to V
DD
if a pull-up has been employed.
(4) V
SS
will again be output when V
DD
rises above the minimum operating voltage. V
SS
will continue to be output even when
V
DD
surpasses -V
DET
, as long as it does not exceed the release voltage +V
DET
.
(5) When V
DD
rises above +V
DET
(B in Figure 10), the Nch transistor goes OFF, the Pch transistor goes ON, and V
DD
appears at the output.
