Maxim Integrated MAX793TCPE+ Battery Backup IC

The MAX793TCPE+ from Maxim Integrated is a high-performance, low-power microprocessor (µP) supervisory circuit designed 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 with +5V-powered circuits.

Key Features:

• Precision Monitoring: This device offers precision monitoring of +5V power-supply voltages with a factory-trimmed reset threshold voltage, ensuring reliable operation of the connected µP system.
• Backup Battery Control: The MAX793TCPE+ includes a backup battery control feature that automatically switches to the backup battery when the primary power supply voltage drops, seamlessly maintaining power to the µP memory, real-time clock, and other critical circuitry.
• Low Power Consumption: Designed for power-sensitive applications, this IC consumes minimal power, which helps extend the life of backup batteries and reduces overall power usage.
• Manual Reset Input: An additional manual reset input allows for a push-button reset, providing an extra layer of system control and user interaction.
• Power-Fail Warning: The IC includes a power-fail warning that signals when the power supply drops below a designated threshold, allowing the system to execute shutdown procedures to prevent data loss or corruption.

Applications:

The MAX793TCPE+ is ideal for a wide range of applications, including:

• Computers and Controllers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Critical µP Power Monitoring
