DESCRIPTION  
The DS1233A EconoReset monitors two vital conditions for a microprocessor: power supply and external  
override. A precision temperature-compensated reference and comparator circuit are used 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 350ms to allow the power supply and  
processor to stabilize. The second function of the DS1233A is pushbutton reset control. The DS1233A  
debounces a pushbutton closure and will generate a 350ms reset pulse upon release.  
OPERATION — POWER MONITOR  
The DS1233A 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 350ms after the power supply has reached the selected tolerance. This allows the power  
supply and microprocessor to stabilize before RST is released.
