FEATURES
Records the total time that the Event Input has
been active and the number of events that
have occurred
Elapsed Time Counter to monitor event
durations with quarter second resolution
Built in 32 bit non-volatile Total Time
Accumulator Register (34 years)
Non-volatile 17-bit Event Counter records the
total number of times an event has occurred
Programmable 32 bit non-volatile alarm trip
point to trigger Alarm# output
Alarm# output to alert the user that the total
accumulated time limit has been reached
Calibrated, Temperature Compensated RC
time base (accurate to 1% typ)
Stores the contents of the Elapsed Time
Counter with the previous total and
increments the event counter at the end of
each event or power down
Reset Enable bit to allow the device to be
cleared to zero, if desired
10 bytes of write protectable EEPROM user
memory
Write Disable bit to prevent the memory from
being changed or erased
Anti-Glitch filter will prevent noise spikes
from triggering false events on the Event
Input
2-wire serial communication
Wide power supply range (2.5V – 5.5V)

DESCRIPTION
The DS1682 is an integrated elapsed time recorder that will provide the total amount of time that an event
is/has been active since the DS1682 was last reset to zero via the 2-wire bus. When the total time
accumulated is equal to the preset alarm trip point and the polarity bit is set to a zero, the Alarm# output
will become active to alert the user, or with the polarity bit set to a one, the Alarm# output will become
inactive when the values match. This is ideal for applications such as monitoring the total amount of time
that something is turned on or in operation, how long something has been used, or the total number of
uses since the last calibration or repair.
