The MAX695EPE from Maxim Integrated is a robust, versatile microprocessor (µP) supervisory circuit designed to monitor power supplies and µP activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered systems.

Key Features:

• Power Supply Monitoring: The MAX695EPE ensures that the system's power supply remains within acceptable limits, providing a reset output during power-up, power-down, and brownout conditions. This feature helps prevent erroneous operation when the power supply is inadequate.
• Microprocessor Monitoring: It includes a watchdog timer to reset a microprocessor if it fails to strobe within a preset timeout period. This feature is vital for systems that require high reliability and where program execution errors must be caught promptly.
• Battery Backup: With a battery backup capability, the MAX695EPE switches to a backup battery automatically when the primary power supply fails, ensuring uninterrupted operation of the memory and real-time clock functions in µP systems.
• Low Power Consumption: Designed for power-sensitive applications, it draws minimal current, which is crucial for maximizing battery life in portable devices.

Applications:

The MAX695EPE is suitable for a wide range of applications, including:

• Computers and Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
• Embedded Systems

Technical Specifications:

Overall, the MAX695EPE is a reliable choice for system designers looking for a µP supervisory circuit that can help enhance system integrity and extend product life.
