DESCRIPTION  
The DS1813 EconoReset uses a precision temperature 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 150 ms to allow the power supply and  
processor to stabilize.  
The DS1813 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is  
generated upon release and will be held in reset output low for typically 150 ms.
