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.
