Maxim Integrated MXD1210ESA+T Memory Backup Battery Controller

The MXD1210ESA+T from Maxim Integrated is a highly efficient, compact, and reliable memory backup battery controller that is designed to maintain power to nonvolatile RAM, real-time clocks (RTC), and other essential digital logic circuits during a main power failure. This innovative component ensures that critical data is preserved and system states are maintained in the event of power interruptions.

The MXD1210ESA+T operates by automatically switching to a backup battery when the main power supply voltage drops below a predefined threshold. Its swift changeover to the backup battery ensures that the connected memory and logic circuits continue to operate without interruption or data loss. This feature is particularly important for applications in which data integrity is crucial, such as industrial control systems, data loggers, and portable medical devices.

One of the key advantages of the MXD1210ESA+T is its low power consumption. It boasts a quiescent current of only 1µA, which is ideal for battery-powered applications where energy efficiency is paramount. This low current draw extends the life of the backup battery, ensuring that the system remains operational for longer periods during power outages.

The device comes in a space-saving 8-pin SOIC package, making it suitable for use in space-constrained applications. It is also characterized for operation over a wide temperature range, from -40°C to +85°C, which allows for deployment in environments with extreme temperature variations.

Additional features of the MXD1210ESA+T include a write protection pin that prevents inadvertent writes to memory when switching to battery power, thus safeguarding the integrity of stored data. The component also offers a reset output option that can be used to reset the system when power is restored, ensuring a safe and orderly recovery for the connected circuits.

In summary, the MXD1210ESA+T from Maxim Integrated is a highly reliable and efficient solution for maintaining power to critical memory and logic circuits during main power failures. Its low power consumption, compact form factor, and robust feature set make it an excellent choice for a wide range of applications requiring uninterrupted operation and data preservation.
