■NOTES ON USE
1. Use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent damage
2. The power supply input pin voltage drops by the resistance between power supply and the V
3. When the setting voltage is less than 1.0V, be sure to separate the V
4. Note that a rapid and high fluctuation of the power supply input pin voltage may cause a wrong operation.
5. Power supply noise may cause operational function errors, Care must be taken to put the capacitor between V
6. When there is a possibility of which the power supply input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release operation
6. In N channel open drain output, V

and the Cd pin as the Figure 3 shown below.
at operation of the IC. At this time, the operation may be wrong if the power supply input pin voltage falls below the
minimum operating voltage range. In CMOS output, for output current, drops in the power supply input pin voltage
similarly occur. Moreover, in CMOS output, when the V
the circuit may occur if the drops in voltage, which caused by through current at operation of the IC, exceed the hysteresis
voltage. Note it especially when you use the IC with the V
1.0V to the V
test on the board carefully.

In this case, Rpull should be selected higher or equal to 18kΩ in order to keep the output voltage less than 0.1V during
detection.

For example：when Vpull = 6.0V and V
In this case, Rpull should be selected smaller or equal to 25kΩ in order to obtain output voltage higher than 5.99V
