Superior Upgrade for MAX699  
The LTC699 provides power supply monitoring for  
microprocessor-based systems. The features include mi-  
croprocessor reset and watchdog timing. Precise internal  
voltage reference and comparator circuit monitor the  
power supply line. When an out-of-tolerance condition  
occurs, the RESET output is forced to active low. In  
addition, the RESET output is guaranteed to remain logic  
low even with VCC as low as 1V.  
An internal watchdog timer is also available, which forces  
the RESET output to active low when the watchdog input  
is not toggled prior to the time-out period of 1.6 seconds.
