The DS1632 PC Power-Fail and Reset Controller is designed to do various functions involving battery
backup and other functions typically accomplished with discrete components. The DS1632 provides a
32.768 kHz battery-backed crystal oscillator and switched V CC /V BAT power via V CCO for the real time
clock function located in accompanying chip sets. In addition, the DS1632 provides for reset on both
