DESCRIPTION  
The DS1233D EconoReset uses a precision temperature-compensated reference and comparator circuit to  
monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal  
power-fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance  
condition, the reset signal is kept in the active state for approximately 350 ms to allow the power supply  
and processor to stabilize.  
OPERATION - POWER MONITOR  
The DS1233D provides the functions of detecting out-of-tolerance power supply conditions and warning  
a processor-based system of impending power failure. When VCC is detected as out of tolerance as  
defined by the tolerance of the part selected, the RST signal is asserted. On power-up, RST is kept active  
for approximately 350 ms after the power supply has reached the selected tolerance. This allows the  
power supply and microprocessor to stabilize before RST is released.
