Maxim Integrated MAX793TCSE+T Battery Backup IC

The MAX793TCSE+T from Maxim Integrated is a sophisticated integrated circuit (IC) designed to provide reliable battery backup management in a wide range of applications. This IC is part of Maxim's extensive portfolio of power management solutions, tailored to ensure the smooth operation of electronic systems during power failures or when primary power sources are unavailable.

At the heart of its functionality, the MAX793TCSE+T offers a low-power supply monitor with a battery backup controller. This feature ensures that critical data and functions are preserved during unexpected power interruptions by automatically switching to a backup battery when the main power supply falls below a designated threshold. The seamless transition between power sources is crucial in applications such as real-time clocks, microcontrollers, and other memory or logic circuits that must remain operational at all times.

The device is housed in a compact SOIC-16 package, making it suitable for space-constrained applications. Its small footprint allows designers to integrate it into their systems without significantly impacting the overall size of their designs. The MAX793TCSE+T operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance in various environments and applications.

Key features of the MAX793TCSE+T include:

• Automatic switchover to battery backup
• Low quiescent current, which extends battery life
• Adjustable power-fail input threshold for versatile applications
• 40nA battery supply current when in backup mode
• SOIC-16 package for compact integration
• Wide operating temperature range for robust performance

This IC is also designed with a write protection feature that safeguards memory integrity by preventing inadvertent writes during power transitions. The MAX793TCSE+T's reliability and performance make it an excellent choice for mission-critical systems where data integrity and uptime are paramount.

Whether you're designing for industrial controls, portable devices, or any other application requiring dependable battery backup, the Maxim Integrated MAX793TCSE+T offers a high-quality solution that engineers can trust to maintain system integrity and ensure continuous operation.
