Key Featrues
Precision Supply-Voltage Monitoring: The MAX817/MAX818/MAX819 series offers precision monitoring at 4.65V (MAX81_L) and 4.40V (MAX81_M), ensuring reliable operation of +5V-powered systems. This feature enhances system stability by accurately detecting voltage drops, preventing data corruption or system crashes in critical applications like battery-powered devices or embedded controllers.
Low Quiescent Supply Current: With a typical quiescent current of just 11µA, these supervisory circuits are highly efficient, making them ideal for portable and battery-powered equipment. This low power consumption extends battery life, reducing the need for frequent recharging or replacement, which is crucial for portable instruments and IoT devices.
Watchdog Timer with 1.6s Timeout: The MAX817 and MAX818 include a watchdog timer that triggers a reset if the system fails to respond within 1.6 seconds. This feature ensures system reliability by recovering from software hangs or hardware faults, making it suitable for applications requiring continuous operation, such as industrial controllers or critical µP monitoring.
Battery-Backup Power Switching: These devices support seamless battery-backup power switching, even when the battery voltage exceeds VCC. This capability ensures uninterrupted operation during power failures, making them ideal for applications like data loggers, medical devices, or any system requiring backup power for critical functions.
Manual Reset Input (MAX819): The MAX819 includes a manual reset input, allowing users to force a system reset when needed. This feature provides additional control over system operation, enhancing usability in debugging, testing, or emergency scenarios, particularly in intelligent instruments or embedded systems.
