Product Overview: MAX708ESA+ from Maxim Integrated

The MAX708ESA+ is a microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy needed for managing power functions and ensuring stable operation. This supervisory circuit is particularly suitable for use in computers, controllers, intelligent instruments, and portable battery-powered equipment.

Key Features

• Voltage Monitoring: The MAX708ESA+ monitors the system voltage and ensures that it remains within acceptable thresholds, thereby protecting the system from undervoltage conditions.
• Reset Output: It features an active-low reset output that remains asserted until the system voltage has stabilized after an undervoltage condition, ensuring the system restarts from a known state.
• Manual Reset: A manual reset input allows for a system reset to be triggered with an external switch or software command, providing additional control to the system operator or maintenance personnel.
• Low Power Consumption: With its low power consumption design, the MAX708ESA+ is ideal for battery-operated devices, helping to extend the overall battery life.
• Watchdog Timer: The built-in watchdog timer ensures that the system continues to operate as expected by monitoring the system's activity and triggering a system reset in case of malfunction.
