DS1682 - Total-Elapsed-Time Recorder

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.

Features

  • Records the Total Time That the Event Input Has Been Active and the Number of Events That Have Occurred.
  • 32-Bit, Nonvolatile, Elapsed Time Counter (ETC) Monitors Event Duration with Quarter-Second Resolution and Provides 34 Years of Total Time Accumulation.
  • Programmable Elapsed Time ALARM Output.
  • Nonvolatile, 17-Bit Event Counter Records the Total Number of Times an Event has Occurred.
  • Calibrated, Temperature-Compensated RC Time Base Accurate to.

DS1682 Total-Elapsed-Time Recorder with Alarm 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.
