产品概述

The DS1682S+T&R is a total-elapsed-time recorder with alarm in 8 pin NSOIC package. This integrated elapsed-time recorder containing a factory-calibrated temperature compensated RC time base that eliminates need for an external crystal. It uses an EEPROM technology to maintain data in absence of power. It detects & records number of events on EVENT pin & total cumulative event time since IC was last reset to 0. It has 32bit, non-volatile, elapsed time counter (ETC) monitors event duration with quarter-second resolution and provides 34 years of total time accumulation. The ALARM (complementary) pin alerts user when total time accumulated equals user-programmed alarm value. The polarity of open-drain ALARM pin can be programmed to either drive low or to become high impedance upon an alarm condition. The IC is ideal for applications that monitor 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 cal
  • Supply voltage range is 2.5V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Records total time that the event input has been active & the number of events that have occurred
  • Device requires no backup power source
  • Programmable elapsed time ALARM(complementary) output, 2-wire serial communication
  • Non-volatile, 17bit event counter records the total number of times an event has occurred
  • Calibrated, temperature-compensated RC time base accurate to 2% typical
  • 10bytes of EEPROM user memory
  • Write disable function to prevent the memory from being changed or erased
  • Useful in time of use warranty, calibration, repair and maintenance applications
