• MXD1818 Offers Improved Performance over  
the DS1818  
DESCRIPTION  
The DS1818 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 150 ms to allow the power supply  
and processor to stabilize.  
The DS1818 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is  
generated upon release and the DS1818 output will be held in reset output low for typically 150 ms.
