A typical circuit example is shown in Figure 1, and the timing chart of Figure 1 is shown in Figure 2 on the next page.

① As an early state, the input voltage pin is applied sufficiently high voltage to the release voltage and the delay capacitance

(Cd) is charged to the input pin voltage.

delay capacitance discharge is turned ON, and starts to discharge the delay capacitance.

For the internal circuit, which

uses the delay capacitance pin as power input, the reference voltage operates as a comparator of VIN, and the output

③ While the input pin voltage keeps below the detect voltage, and 0.7V or more, the delay capacitance is discharged to the

④ While the input pin voltage drops to 0.7V or less and it increases again to 0.7V or more, the output voltage may not be able to

maintain the “Low” level.

Such an operation is called “Unspecified Operation”, and voltage which occurs at the output pin
