DESCRIPTION
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. ♦ 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 FEATURES
