Product Overview: Maxim Integrated MAX701ESA-T

The MAX701ESA-T from Maxim Integrated is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and precision with a minimum of external components, which is ideal for cost and space-sensitive applications.

This supervisory circuit ensures that the µP is only operational when the power supply voltage is within an acceptable range. It accomplishes this by issuing a reset to the µP during power-up, power-down, and brownout conditions. Once the power supply voltage exceeds the reset voltage threshold, the MAX701ESA-T maintains the reset output in the active state for approximately 140ms after the supply voltage reaches the threshold level, thus allowing the power supply and µP to stabilize before the system starts.

Key Features

• Precision Voltage Monitoring: The device features a precision voltage monitor that keeps a close eye on the system voltage levels, ensuring the µP operates in the desired voltage range.
• Power Supply Glitch Immunity: Power supply glitches are filtered out, preventing unnecessary resets which could otherwise disrupt the normal operation of the system.
• Manual Reset Capability: An external input is provided to manually trigger a system reset, allowing for additional system management and diagnostic capabilities.
• Low Power Consumption: The MAX701ESA-T is designed for low power consumption, which is crucial for battery-powered and energy-efficient applications.
• Wide Operating Temperature Range: It operates over a wide temperature range, making it suitable for various environments and applications.

Applications

The MAX701ESA-T supervisory circuit is versatile and can be used in a wide array of applications, including:

• Computers and Servers
• Embedded Systems
• Data Storage Devices
• Portable/Battery-Powered Equipment

With the MAX701ESA-T, designers can ensure their systems maintain integrity and reliability through all sorts of conditions, safeguarding data and improving overall system performance.

Maxim Integrated's commitment to quality and reliability is evident in the MAX701ESA-T, making it a top choice for system designers looking for a supervisory circuit that is both effective and economical.
