DESCRIPTION  
The DS1233M 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 (low) state. When VCC returns to an  
intolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the  
power supply and processor to stabilize.
