GENERAL DESCRIPTION
The DS1682 is an integrated elapsed-time recorder
containing
a
factory-calibrated,
temperature-
compensated RC time base that eliminates the need
for an external crystal. Using EEPROM technology
to maintain data in the absence of power, the DS1682
requires no backup power source. The DS1682
detects and records the number of events on the
EVENT pin and the total cumulative event time since
the DS1682 was last reset to 0. The
ALARM pin
alerts the user when the total time accumulated
equals the user-programmed alarm value. The
polarity of the open-drain
ALARM pin can be
programmed to either drive low or to become high
impedance upon an alarm condition. The DS1682 is
ideal for applications that monitor the total amount of
time that a device has been in operation and/or the
number of uses since inception of service, repair, or
the last calibration.
APPLICATIONS
High-Temp, Rugged, Industrial Applications Where
Vibration or Shock Could Damage a Quartz
Crystal
Any System Where Time-of-Use is Important
