Product Overview: MAX793SCSE+ from Maxim Integrated

The MAX793SCSE+ is a high-performance, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered systems, portable computers, and other microprocessor-based equipment.

Key Features

• Precision Monitoring: This device offers precision monitoring of +3.3V, +5V, and adjustable voltage supplies, ensuring that the system is operating within safe voltage levels.
• Reset Output: The MAX793SCSE+ provides a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring proper system reset.
• Battery Backup Switching: It includes a battery backup switching function that automatically switches to the backup battery when the main power supply fails, maintaining critical system operations.
• Low Power Consumption: With its low supply current of 40µA (typical), the device is ideal for power-sensitive applications.
• Manual Reset: A manual reset input allows for a reset to be triggered with an external pushbutton or logic signal, providing an additional layer of system control.

Applications

The MAX793SCSE+ is versatile and can be used in various applications, including:

• Computers and servers
• Embedded systems
• Portable/battery-powered equipment
• Industrial controllers

Technical Specifications
