Maxim Integrated DS1672
The DS1672 incorporates a 32-bit counter and power-monitoring functions. The 32-bit counter is designed to count seconds and can be used to derive time-of-day, week, month, month, and year by using a software algorithm. When an out-of-tolerance condition occurs, an internal power-fail signal is generated that forces the reset to the active state.| Part No. | DS1672 |

GENERAL DESCRIPTION
A precision, temperature-compensated reference and comparator circuit monitors the status of VCC. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for a period of time to allow the power supply and processor to stabilize. TYPICAL OPERATING CIRCUITFEATURES
