Description

The DS1672S-33 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. DS1672S-33 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 Laboratories(UL) Recognized• -40°C to +85°C Operating Range
