MAX6814XK+T

The MAX6814XK+T is a watchdog timer circuit in 5 pin SC-70 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. Typical applications include computers and controllers, embedded controllers, intelligent instruments and critical μP monitoring.

• Supply voltage range is 2.25V to 5.5V
• Operating temperature range from -40°C to 85°C
• Operating current is 4μA
• Watchdog timer with 1.6s timeout
• Push-pull active-low watchdog output
