The MAX800MCSE+ from Maxim Integrated is a state-of-the-art microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with +5V-powered circuits.

Key Features

• Power Supply Monitoring: This device ensures that the µP is only powered up in a proper state. It monitors the power supply voltage and keeps the µP in reset until that voltage reaches a stable condition. Afterward, it continues to monitor the supply to ensure its operation within acceptable parameters.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered with an external switch or logic signal, offering additional control and security.
• Backup Battery Switchover: The MAX800MCSE+ includes a backup battery switchover feature that ensures uninterrupted operation if the primary power supply fails, making it ideal for critical systems where data integrity is paramount.
• Low Power Consumption: Its low power consumption makes it suitable for portable and power-sensitive applications, ensuring that the overall power usage of the system is kept to a minimum.
• Watchdog Timer: The device comes with a watchdog timer that must be periodically reset by the µP. If the µP fails to reset the watchdog, the MAX800MCSE+ assumes that the µP is not functioning correctly and issues a reset signal.

Applications

The MAX800MCSE+ is an ideal component for a wide range of applications, including:

• Computers and Controllers
• Intelligent Instruments
• Automotive Systems
• Critical µP Power Monitoring

Technical Specifications

With a wide operating temperature range and available in a compact 16-pin SO package, the MAX800MCSE+ is a versatile and reliable solution for system management and power supply supervision. Its technical specifications include a threshold voltage typically at 4.65V, ensuring that the µP and other digital systems have a stable and reliable power supply before commencing operation.
