DESCRIPTION  
The DS1231 Power Monitor Chip uses a precise tem-  
perature-compensatedreference circuit whichprovides  
an orderly shutdown and an automatic restart of a pro-  
cessor-basedsystem. Asignalwarningofanimpending  
power failure is generated well before regulated DC  
voltages go out of specification by monitoring high volt-  
age inputs to the power supply regulators. If line isola-  
tion is required a UL-approved opto-isolator can be di-  
rectly interfaced to the DS1231. The time for processor  
shutdown is directly proportional to the available  
hold-up time of the power supply. Just before the  
hold-up time is exhausted, the Power Monitor uncondi-  
tionally halts the processor to prevent spurious cycles  
by enabling Reset as V falls below a selectable 5 or  
CC  
10 percent threshold. When power returns, the proces-  
sor is held inactive until well after power conditions have  
stabilized, safeguarding any nonvolatile memory in the  
system from inadvertent data changes.
