| DS9034PC/PCI PowerCap www.maxim-ic.com FEATURES Provides 10 years of battery backup power for Nonvolatile (NV) SRAMs in the PowerCap Module (PCM) package Snaps directly onto a surface-mounted PowerCap module base to form a complete NV SRAM module Attaches after module base has been surfacemounted to protect lithium battery from the high temperatures of reflow soldering Maintains mechanical and electrical connection with module base even during severe shock and vibration stresses Detachment feature allows easy removal using a regular screwdriver Periodic replacement allows NV SRAM module life to be extended indefinitely Optional industrial temperature range of -40C to +85C, designated PCI Compatible with these PowerCap module bases: DS1230YP/ABP/WP DS1245YP/ABP/WP DS1250YP/ABP/WP DS1330YP/ABP/WP DS1345YP/ABP/WP DS1350YP/ABP/WP PACKAGE OUTLINE GND VBAT TOP VIEW SIDE VIEW PIN DESCRIPTION VBAT GND - +3V Battery Output - Ground ABSOLUTE MAXIMUM RATINGS Operating Temperature: 0C to +70C, -40C to +85C for PCI parts Storage Temperature: -40C to +70C, -40C to +85C for PCI parts BATTERY CHARACTERISTICS Nominal Voltage Nominal Capacity Chemistry Data Retention Life 3V 130mAh Li(CF)X 10 Years (25C) DESCRIPTION The DS9034PC PowerCap is a snap-on lithium power source for NV SRAMs in Dallas Semiconductor's directly surface-mountable PowerCap module base package. After a PowerCap module has been soldered in place and cleaned, the DS9034PC PowerCap is snapped onto the base to form a complete NV SRAM module. The PowerCap is keyed to prevent incorrect attachment and is designed to maintain mechanical and electrical contact with its host module base even during severe mechanical shock and vibration. The DS9034PC is easily removed by inserting a regular screwdriver into the detachment feature and prying gently outward and upward to release the PowerCap from the module base. 1 of 3 100102 DS9034PC/PCI POWERCAP ATTACHMENT POWERCAP REMOVAL 2 of 3 DS9034PC/PCI DS9034PC PACKAGE DIMENSIONS PKG DIM A B C D E MIN 0.845 0.955 0.210 0.065 0.065 INCHES NOM 0.850 0.960 0.215 0.070 0.070 MAX 0.855 0.965 0.220 0.075 0.075 ATTENTION: BATTERY COMPONENT The DS9034PC contains a lithium battery. Do not short, ground or apply external voltages to the electrical portions of this device. Do not expose to temperatures over +85C. Do not subject this device to any type of cleaning process. Store only in non-conductive containers. Failure to observe these precautions may result in battery discharge or decreased battery life. 3 of 3 |
