DS9034PCI

Overview

The DS9034PCI is a 34-pin PowerCap module manufactured by Analog Devices Inc./Maxim Integrated. It integrates dual 3V surface-mount memory batteries with a PowerCap integrated circuit to provide battery backup power for nonvolatile timekeeping RAMs. The device snaps directly onto compatible surface-mounted PowerCap Module boards and includes a detachment feature for easy removal.

Feature Summary

• Provides ten years of battery backup power for nonvolatile timekeeping RAMs
• Snaps directly onto surface-mounted PowerCap Module boards
• Features a detachment mechanism allowing for easy removal

Applications

• Battery backup for nonvolatile timekeeping RAMs
• Compatible with 34-pin PowerCap Module boards such as DS1386P, DS1486P, and DS1643P

Procurement Notes

Verify the specific suffix (PCI) against official documentation to confirm pinout and compatibility. Confirm lifecycle status as obsolete before design-in. Ensure the target board supports the 34-pin PowerCap Module form factor. Check RoHS compliance history if required for current manufacturing standards.

Selection Notes

Select this component when a compact, snap-on battery solution is needed for maintaining timekeeping data in static RAM. It is designed specifically for use with Maxim Integrated's PowerCap Module boards. Verify that the application requires the specific voltage and capacity characteristics provided by the dual 3V surface-mount cells within the module.

Part Context

This part belongs to the PowerCap Module family from Maxim Integrated, designed for low-power battery backup applications. It serves as a self-contained power source for volatile memory components, ensuring data retention during main power loss. The module format simplifies assembly compared to discrete battery solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product lifecycle is listed as obsolete, alternative components must be sourced through secondary markets or evaluated based on mechanical and electrical compatibility with existing designs.
