The MAX706RESA+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

This supervisory circuit significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX706RESA+T offers several essential functions to safeguard your system's integrity: a reset output during power-up, power-down, and brownout conditions, and a watchdog timer to ensure the µP is operating correctly.

This device is available in an 8-pin SO package and is suitable for a broad range of applications, including computers, controllers, intelligent instruments, critical µP and µC power monitoring, and portable/battery-powered equipment.

Key Features:

• Precision Monitoring: Accurate monitoring of +5V power-supply voltages with a factory-set reset threshold voltage.
• Reset Output: The reset output is guaranteed to be in the correct state for V_CC down to 1V.
• Watchdog Timer: A watchdog timer with a 1.6-second timeout ensures the system's microprocessor is running correctly.
• Manual Reset: A manual reset feature allows for a simple, push-button reset, providing an additional layer of system control.
• Power-Fail Comparator: Detects low voltage conditions, allowing the system to take action before power failure occurs.
• Low Power Consumption: Designed for low power consumption to support battery-powered applications.
• Wide Operating Temperature: Functions across a broad temperature range from -40°C to +85°C.

Applications:

• Computers and Servers
• Embedded Systems
• Intelligent Instruments
• Battery-Powered Devices
• Industrial Controllers

The MAX706RESA+T is a testament to Maxim Integrated's commitment to providing integrated circuits that enhance the performance and longevity of electronic systems, ensuring they operate with precision and stability under various conditions and use cases.
