Key Featrues

Precision Supply Voltage Monitoring: The MAX690A/MAX802L/MAX805L series offers precise supply voltage monitoring at 4.65V, ensuring reliable operation in critical µP systems. This feature enhances system accuracy and reliability, particularly in applications requiring strict voltage thresholds.
Reset Time Delay of 200ms: The built-in reset time delay ensures a stable reset signal, preventing false triggering during power fluctuations. This feature improves system stability and reduces the risk of unintended resets in power-sensitive applications.
Watchdog Timer with 1.6s Timeout: The watchdog timer monitors system activity and triggers a reset if the system fails to respond within 1.6 seconds. This feature enhances system reliability by detecting and recovering from software or hardware faults.
Battery-Backup Power Switching: The device supports battery-backup power switching, enabling seamless transition to backup power during main power failure. This feature is critical for maintaining uninterrupted operation in battery-powered systems and intelligent instruments.
Low Quiescent Supply Current: With a quiescent supply current of just 200µA (and 50nA in battery-backup mode), the device minimizes power consumption, making it ideal for energy-efficient applications such as battery-powered computers and controllers.
