Maxim Integrated MAX793REPE+ Overview

The MAX793REPE+ 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 system monitoring applications.

Key Features

• Power Supply Monitoring: The MAX793REPE+ ensures that the power supply voltage remains within acceptable limits, providing a precise comparator to monitor the VCC.
• Reset Output: Upon detecting an out-of-tolerance power supply, it asserts a reset signal to prevent system errors. The reset signal remains asserted for a minimum timeout period after VCC has risen back to an acceptable level, ensuring system stability.
• Voltage Monitor for Power-Fail or Low-Battery Warning: A separate comparator with a programmable threshold monitors the voltage level for critical conditions such as power-fail or low-battery scenarios.
• Manual Push-Button Reset Input: An additional feature of the MAX793REPE+ is the manual reset input that allows for a system reset to be triggered with a simple push-button, providing an easy and user-friendly way to reboot the system.
• Backup Battery Switchover: In the event of a main power failure, the device includes a backup battery switchover feature that allows for a seamless transition to a backup power source, ensuring uninterrupted operation.
• Low Power Consumption: The MAX793REPE+ is designed for energy-efficient operation, which is critical for battery-powered devices.

Applications

The versatile nature of the MAX793REPE+ makes it suitable for a wide range of applications, including:

• Computers and Controllers
