It integrates a Lithium Cell and the necessary power-switching and write-protect functions so that an external SRAM or RTC retains data when the main supply drops. The part is housed in a 34-PowerCap Module, a socketed, snap-on package that allows the battery and support circuitry to be replaced without desoldering the memory device underneath. ## Temperature grade and deployment environment Rated for -40°C to 85°C, this is an industrial-temperature device. It fits telecom base stations, outdoor industrial controllers, utility metering, and security systems that need reliable data retention through power loss. It is not qualified for automotive under-hood environments (125°C junction), but the range covers most cabinet and enclosure applications. ## Package and footprint reality The 34-PowerCap Module is a surface-mount package that mates with a matching socket on the PCB — typically the DS9034PCX socket or a footprint compatible with the DS12C887 family. The module snaps onto the base SRAM/RTC device, so the battery and backup controller are field-replaceable. Ground shipment only due to the lithium cell — no air freight for this part.","metaTitle":"DS9034I-PCX+ PowerCap Module, Back-Up Management","metaDescription":"DS9034I-PCX+ from Analog Devices: 34-PowerCap Module, lithium cell backup for SRAM/timekeeping.

It is the drop-in battery/backup module for that socket. Verify the base device's pinout and socket orientation before ordering."},{"question":"What is the battery life of DS9034I-PCX+?","answer":"The DS9034I-PCX+ uses a Lithium Cell. Battery life depends on the load from the attached SRAM/RTC and the ambient temperature. Typical data-sheet estimates for the PowerCap family range from several years to over a decade at room temperature with low-leakage memory. For a specific application, calculate the average current draw of the backed-up device and compare to the cell's rated capacity."},{"question":"What is the difference between DS9034I-PCX+ and DS9034PCX?","answer":"The 'I' in DS9034I-PCX+ denotes the industrial temperature grade (-40°C to 85°C). The standard DS9034PCX (without 'I') is typically rated for commercial temperature range (0°C to 70°C). The package, function, and lithium cell are otherwise the same. Choose the 'I' variant for outdoor or extended-temperature environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS9034I-PCX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS9034I-PCX when reusing this data.
