DS1682 Total-Elapsed-Time Recorder with Alarm
The V
holding capacitor value of 30μF is calculated using the maximum EEPROM write current and
CC
EEPROM write time. This assumes that the V
slew rate allows time from EVENT trip point to V
at
CC
CC
2.5V on the DS1682 is at least t
EW.
Figure 4 shows the DS1682 in a total time-of-use application with power that can be removed at the same
time as the end of the event. In this application, the V
slew rate at power-down is slow with respect to
CC
t
. The external RST IC ends the event as V
begins to drop. V
must remain above 2.5V until the
EW
CC
CC
end of t
.
