5-Pin Watchdog Timer Circuit

General Description

Features

● 4µA Operating Current

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.

● 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

The MAX6814 consumes only 4µA of supply current and

is fully specified over the extended temperature range.
