Pin-Selectable Watchdog Timers  
General Description  
Features  
The MAX6369–MAX6374 are pin-selectable watchdog  
timers that supervise microprocessor (µP) activity and  
signal when a system is operating improperly. During  
normal operation, the microprocessor should repeated-  
ly toggle the watchdog input (WDI) before the selected  
watchdog timeout period elapses to demonstrate that  
the system is processing code properly. If the µP does  
not provide a valid watchdog input transition before the  
timeout period expires, the supervisor asserts a watch-  
dog (WDO) output to signal that the system is not exe-  
cuting the desired instructions within the expected time  
frame. The watchdog output pulse can be used to reset  
the µP or interrupt the system to warn of processing  
errors.

The MAX6369–MAX6374 are flexible watchdog timer  
supervisors that can increase system reliability through  
notification of code execution errors. The family offers  
several pin-selectable watchdog timing options to  
match a wide range of system timing applications:

• Watchdog startup delay: provides an initial delay  
before the watchdog timer is started.
