DESCRIPTION
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 VCC/VBAT power via VCCO for the real time clock function located in accompanying chip sets. In addition, the DS1632 provides for reset on both power-up and via pushbutton input, power-fail status signals for the processor, and low battery warning signals.
