DS1682S+

The DS1682S+ is a Total-Elapsed-Time Recorder with alarm. The recorder 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 recorder requires no backup power source. This detects and records the number of events on the EVENT pin and the total cumulative event time since the recorder 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. This is ideal for applications that monitor the total amount of time that a device has been in operation or the number of uses since inception of service, repair or the last calibration.

• Records total time that event input has been active, number of events that have occurred
• 32-bit, nonvolatile/elapsed time counter (ETC) monitor event duration with quarter-second resolution
• Programmable elapsed time active-low alarm output
• Non-volatile 17-bit event counter records 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 memory from being changed or erased
• 2-wire Serial communication
