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.
The MAX6814 consumes only 4µA of supply current and
is fully specified over the extended temperature range.
