DS1683S+

The DS1683S+ is a total-elapsed-time and event recorder with alarm in 8 pin NSOIC package. The 32bit, non-volatile, elapsed time counter (ETC) monitors event duration with quarter-second resolution and provides 34 years of total time accumulation. It uses an EEPROM technology to maintain data in absence of power. It detects, records the number of falling edge transitions on the EVENT pin as well as the total cumulative time that the EVENT pin is held high. The ALARM pin alerts user when total time accumulated equals or exceeds user-programmed alarm value or when total number of events equals or exceeds user-programmed alarm value. The polarity of open-drain ALARM pin can be programmed to either drive low or become high impedance upon an alarm condition. It is ideal for applications that monitor total amount of time a device has been in operation and/or the number of uses since inception service, repair or last calibration.

• Supply voltage range is 2.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• Records total time the event input has been active high & number of events that have occurred
• Device requires no backup power source
• Non-volatile 16bit event counter records the number of falling edges seen by the EVENT pin
• Calibrated, low temperature coefficient RC time base eliminates need for an external crystal
• 16 bytes of user EEPROM
• Password protection scheme (4 bytes)
• I2C compatible interface
