DS1682

Total-Elapsed-Time Recorder

with Alarm

General Description

Beneﬁts and Features

● Records the Total Time That the Event Input Has

Been Active and the Number of Events That Have

Occurred

The DS1682 is an integrated elapsed-time recorder con-

taining 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 num-

ber 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 accu-

mulated 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.

● 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 2% Typical

● 10 Bytes of EEPROM User Memory

● Write Disable Function to Prevent the Memory from

Being Changed or Erased

Applications

● 2-Wire Serial Communication

●

High-Temp, Rugged, Industrial Applications Where

Vibration or Shock Could Damage a Quartz Crystal

Any System Where Time-of-Use is Important

(Warranty Tracking)

● Wide 2.5V to 5.5V Power-Supply Range

● Useful in Time-of-Use Warranty, Calibration, Repair,

●

and Maintenance Applications
