The delay time is set by the external capacitor.
But the discharge overcurrent release delay time (t
DIOVR
) and charge overcurrent release delay time (t
CIOVR
) are
calculated by discharge overcurrent detection delay time (t
DIOV
) and charge overcurrent detection delay time (t
CIOV
) as
the following equations. 1 [ms] (typ.) is the internal delay time of the S-8205A Series.

= t

Moreover, refer to "7.

for calculational methods of delay times.
