Maxim Integrated MAX794CPE Microprocessor Voltage Monitor

The MAX794CPE is a sophisticated microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. It is engineered to maintain system integrity by monitoring the power supply voltage in µP and digital systems. This ensures that the system operates reliably by providing a reset signal to the µP during power-up, power-down, and brown-out conditions.

Key Features

• Precision Voltage Monitoring: The device precisely monitors 5V, 3.3V, and other voltage levels, which is crucial for systems that require consistent and accurate power supply levels.
• Power Supply Glitch Immunity: The MAX794CPE provides a stable reset output even during power supply transients, ensuring the µP is not mistakenly reset due to brief voltage glitches.
• Manual Reset Capability: An external manual reset input allows for a system reset to be initiated with an external switch or logic signal.
• Low Power Consumption: Designed for power-sensitive applications, this device consumes minimal power, thus contributing to the overall energy efficiency of the system.
• Reset Time Delay: The device features an adjustable reset timeout period, which can be set by an external capacitor to ensure the system has adequate time to stabilize before the µP starts operating.

Applications

The MAX794CPE is ideal for use in a wide range of applications where reliable voltage monitoring is crucial. These include:

• Computers and Servers
• Embedded Systems
• Industrial Controllers
• Portable/Battery-Powered Equipment
• Telecommunications Systems

Technical Specifications

• Package Type: 16-Pin Plastic DIP
• Operating Temperature Range: -40°C to +85°C
• Supply Voltage Range: Typically 4.75V to 5.5V for standard 5V monitoring
• Reset Threshold Accuracy: ±1.5% over temperature

The MAX794CPE from Maxim Integrated represents a reliable solution for system designers looking to enhance the operational stability of their microprocessor-based systems. With its precision monitoring and low power consumption, it's a valuable component for any application requiring vigilant voltage supervision.
