denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2:
Quiescent current is measured during push-button reset.
Note 3:
Only applies to 16-pin version.
Note 4:
Although the V

threshold voltages have a specification tolerance, they are guaranteed by
design and tested in production never to overlap.
Note 5:

s while in backup mode.
Note 6:
Fast recharge factor is defined as the ratio of charge replenished to
the NiCd battery during fast recharge to the charge withdrawn from the
NiCd battery during backup.
Note 7:
The LTC1559 switches automatically between the low and high
operating current levels. See Applications Information for more details.
