Operation
1. Basic Operation: CMOS Output (Active Low)
1-1. When the power supply voltage (VDD) is higher than the release voltage (+VDET), the Nch transistor is
OFF and the Pch transistor is ON to provide VDD (high) at the output. Since the Nch transistor N1 in
Figure 14 is OFF, the comparator input voltage is

1-2. When the VDD goes below +VDET, the output provides the VDD level, as long as the VDD remains above
the detection voltage
VDET. When the VDD falls below VDET (point A in Figure 15), the Nch
transistor becomes ON, the Pch transistor becomes OFF, and the VSS level appears at the output. At
this time the Nch transistor N1 in Figure 14 becomes ON, the comparator input voltage is changed to

1-3. When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to
the VDD when the output is pulled up to the VDD.
1-4. The VSS level appears when the VDD rises above the minimum operating voltage. The VSS level still
appears even when the VDD surpasses VDET, as long as it does not exceed the release voltage
+VDET.
1-5. When VDD rises above +VDET (point B in Figure 15), the Nch transistor becomes OFF, and the Pch
transistor becomes ON, and VDD appears at the output after the delay time (tD) counted by the delay
circuit.
