DESCRIPTION
The DS1632 PC Power Fail and Reset Controller is de-
signed to do various functions involving battery backup
and other functions typically accomplished with discrete
components. The DS1632 provides a 32.768 KHz bat-
tery backed up crystal oscillator and switched V

power via V
CCO
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. The DS1632 is capable of
detecting power failure at both the 5% and 10% power
supply tolerances, and the reset pulse width can be set
for either 95 ms or 190 ms. The device is designed to
connect directly to popular laptop and notebook chip
sets which eliminates the need for discrete components
and reduces cost.
