1 / 15 page 1 of 15 REV: 031406 GENERAL DESCRIPTION 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. A precision, temperature-compensated reference and comparator circuit monitors the status of VCC. When an out-of-tolerance condition occurs, an internal power-fail signal is generated that forces the reset to the active state. 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. FEATURES 32-Bit Counter I2C* Serial Interface Automatic Power-Fail Detect and Switch Circuitry Power-Fail Reset Output Low-Voltage Oscillator Operation (1.3V min) Trickle-Charge Capability Underwriters Laboratory (UL) Recognized -40 °C to +85°C Operating Temperature Range PIN CONFIGURATION *Purchase of I 2C components from Maxim Integrated Products, Inc., or one of its sublicensed Associated Companies, conveys a license under the Philips I 2C Patent Rights to use these components in an I 2C system, provided that the system conforms to the I 2C Standard Specification defined by Philips.
