Prevent Unwanted Resets During Testing with Precision-Controlled Watchdog Management
Watchdog Kickers
Arxtron Watchdog Kicker Module
Arxtron’s Watchdog Kicker Module is a compact, board-level solution designed to monitor microcontroller and embedded system activity in functional testers, automated equipment, and safety-critical applications. This module ensures operational reliability by resetting or interrupting systems that become unresponsive due to software errors, lockups, or timing failures.
Engineered for seamless integration into Arxtron’s functional test fixtures and control panels, it supports configurable timeout intervals, low power operation, and simple connectivity to test control units, power supplies, or DUTs. Whether you’re protecting an in-house test controller or embedded target board, Arxtron’s watchdog solution enhances stability, uptime, and safety.
Applications & Benefits
Embedded System Supervision
Continuously monitors system “heartbeat” signals to detect lockups and initiate auto-recovery
Reliable Reset Triggering
Automatically resets the system when the heartbeat fails to meet configured timing thresholds
Customizable Timeout Periods
Select fixed or variable timeout intervals based on system latency and stability needs
Fixture and Bench Integration
Easily mounts inside test fixtures, ATE racks, or lab setups with minimal wiring and setup
Supports Manual Override
Optional manual reset and disable features available for debug or maintenance use
