NOTE
1. Voltage referenced to ground.
2. Outputs are open.
3. The IRQ, PWR, and RST outputs are open drain.
4. Battery switch over occurs at the battery terminal voltage level.
5. The DS1511 will keep time to an accuracy of
±
1 min./month during data retention time for the period of t
DR
.
6. t
DR
is the amount of time that the internal battery can power the internal oscillator and internal registers of the
DS1511.
7. If V
PF
is less than V
BAT
and V
BAUX
, the device power is switched from V
CC
to the greater of V
BAT
and V
BAUX
when
V
CC
drops below V
PF
. If V
PF
is greater than V
BAT
and V
BAUX
, the device power is switched from V
CC
to the larger
of V
BAT
and V
BAUX
when V
CC
drops below the larger of V
BAT
and V
BAUX
.
8. Real–Time Clock Modules can be successfully processed through conventional wave–soldering techniques as
long as temperature exposure to the lithium energy source contained within does not exceed +85
°
C. Post solder
cleaning with water washing techniques is acceptable, provided that ultrasonic vibration is not used.
