Maxim Integrated MAX708TEPA+ Microprocessor Supervisory Circuit

The Maxim Integrated MAX708TEPA+ is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected behavior in digital systems. This compact and efficient device is essential for applications where consistent operation and data integrity are critical.

The MAX708TEPA+ monitors the power supply voltage of µP and digital systems, providing a quick response if the voltage falls below a preset threshold. This feature ensures that the system can initiate proper shutdown procedures, preventing data loss and possible hardware damage. It is ideal for use in embedded systems, controllers, and portable electronics where power conditions can be unpredictable.

Key Features:

• Voltage Monitoring: Precision monitoring of the power supply voltage with factory-set reset threshold voltages.
• Reset Output: The device generates a reset signal when the VCC supply voltage declines below the preset threshold, holding the reset for at least 140ms after VCC has risen above the reset threshold, ensuring a proper system reset.
• Manual Reset: Includes a manual reset feature that allows for a reset to be asserted at any time by the user or system.
• Low Power Consumption: Designed for low power consumption, the device is suitable for battery-powered applications where power efficiency is paramount.
• Watchdog Timer: A watchdog timer is built in to monitor the system operation and assert a system reset if the software fails to provide a periodic signal, indicating system functionality.

Applications:

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

The MAX708TEPA+ is available in an 8-pin DIP package, making it easy to integrate into various circuit designs. Its operating temperature range from -40°C to +85°C ensures reliable performance in a wide range of environmental conditions. With Maxim Integrated's reputation for quality and reliability, the MAX708TEPA+ supervisory circuit is an excellent choice for safeguarding your digital systems.
