Note :
The delay circuit current is controlled by the set current circuit within the IC.
Delay time depends upon the capacity of the external condensor. Approximate delay time can be calculated using the following formula :
TD ( msec ) = 1.8 x C ( nF )

Note :
The supply current (ISS) value of the entire IC is the IC's internal supply current value.
( This does not include current flowing through externally connected components nor
the input current through the detect pins of voltage detectors 1, 2 )
