Maxim Integrated MAX793RESE+T Battery Backup IC

The Maxim Integrated MAX793RESE+T is a sophisticated IC designed to provide reliable battery backup management for memory and real-time clock (RTC) applications. This component is an integral piece of technology for systems that require data preservation during power loss or when the primary power source is unavailable.

Key Features

• Low Power Consumption: The MAX793RESE+T is engineered to conserve power, making it an excellent choice for battery-powered devices where energy efficiency is paramount.
• Automatic Switchover: When the main power supply falls below a certain threshold, the IC automatically switches to the backup battery, ensuring uninterrupted power supply to critical components without manual intervention.
• Power-Fail Input: It features a power-fail input that provides an early warning of an impending power failure, allowing the system to prepare for a switch to backup power.
• Low Battery Supply Current: The device operates with a very low supply current drawn from the battery when in backup mode, thus extending the life of the backup battery.
• Chip-Enable Gating: The inclusion of chip-enable gating prevents data corruption by disabling memory write access during power transitions.

Applications

The MAX793RESE+T is versatile and can be used in a wide range of applications, including:

• Portable Devices
• Embedded Systems
• Networking Equipment
• Industrial Controllers
• Automotive Systems

Technical Specifications

The MAX793RESE+T comes in a 16-pin NSOIC package, which is suitable for surface mount technology (SMT) and offers a compact footprint for space-constrained applications. It operates over a wide temperature range, ensuring reliability and performance even in extreme conditions.
