5-Pin Watchdog Timer Circuit  
________________General Description  
Features  
The MAX6814 is a low-power watchdog circuit in a tiny 5-  
pin SC70 package. This device improves system reliability  
by monitoring the system for software code execution  
errors. When the watchdog input detects a transitional  
edge, the internal watchdog timer clears and restarts,  
then begins counting again. If the watchdog timer  
exceeds the watchdog timeout period (1.6s typ), the  
active-low, push-pull watchdog output asserts for the  
watchdog pulse period (140ms min) to alert the system of  
the fault.  
4µA Operating Current  
Watchdog Timer with 1.6s Timeout  
140ms (min) WDO Pulse Period  
Push-Pull Active-Low WDO  
Fully Specified Over Extended Temperature  
Range  
No External Components  
The MAX6814 consumes only 4µA of supply current and  
is fully specified over the extended temperature range.
