Product Summary
The MAX6814XK+T is a low-power watchdog circuit in a tiny 5-pin SC70 package. The MAX6814XK+T 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 mwatchdog pulse period (140ms min) to alert the system of the fault. The MAX6814XK+T consumes only 4μA of supply current and is fully specified over the extended temperature range.
