DS1260-50

Overview

The DS1260-50 is a SmartBattery backup energy supply module manufactured by Analog Devices Inc./Maxim Integrated. It integrates a lithium cell with an intelligent switching mechanism to provide power to CMOS circuits during primary power loss. The device features automatic reconnection when VCC is applied and electrically disconnects from exposed pins upon command to prevent energy loss during shipping. It includes a recessed pin design to prevent bending and mates directly with the DS1212 Nonvolatile Controller.

Feature Summary

• Intelligent switch isolates the lithium energy source from exposed pins upon command to preserve capacity during handling
• Automatic reconnection of the battery source occurs when VCC is applied
• Recessed pin construction prevents physical damage and bending
• Generates a VCC fail signal to interrupt processors or write-protect memory

Applications

• Backup power for portable electronic equipment
• Nonvolatile memory protection in CMOS systems
• Integration with DS1212 Nonvolatile Controllers for SRAM backup

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as the product may not meet current environmental standards. Check for shipping restrictions related to lithium content, which may limit air transport options. Ensure the specific suffix matches the required energy capacity and interface specifications for the target application.

Selection Notes

Select this module for applications requiring low-cost, reliable backup power for nonvolatile electronics. Consider the 16-pin DIP form factor for compatibility with standard sockets. Evaluate the need for direct mating with the DS1212 controller if backing up multiple SRAMs. Verify that the operating temperature range meets the environmental requirements of the deployment scenario.

Part Context

The DS1260 series belongs to the SmartBattery family designed for portable and nonvolatile equipment. These modules combine a lithium energy source with efficient switching logic. The series allows for simple replacement via standard DIP sockets and provides uninterrupted supply for CMOS devices. The DS1260-50 represents a specific variant within this lineup.
