APPLICATION NOTE 1926
Watchdogs Improve System Reliability―How to Choose the Right
Part

Abstract: Watchdog timers are used to monitor and minimize code execution errors. Internal watchdog timers
are subject to code execution problems, making external watchdog circuits invaluable in preventing system
lockup.

This document provides assistance in selecting the right time of watchdog/supervisory product for different type
of applications and how to apply the circuit without the software code.


Many circuit functions previously realized with dedicated hardware are now implemented in software, du……
