DESCRIPTION

· The bq48SH–28x6 is the top section suitable for any SOIC (DSH) packaged IC, including the bq4802YDSH or bq4802LYDSH parallel real-time clock (RTC) and NVSRAM controller.

· The fully integrated SNAPHAT includes a 6-pF watch crystal and a lithium coin cell with 48 mAh capacity.

· Designed to be attached after the DSH packaged base SOIC has been soldered, preventing the battery and crystal from being over-stressed by soldering temperatures.

FEATURES

· Detachable unit allowing replacement.

· Integrated 6-pF watch crystal for real-time clock operation.

· Integrated lithium coin cell for nonvolatile memory backup.

· Protects battery and crystal from conditions associated with surface mount soldering.

· For use with bq4802YDSH and bq4802LYDSH.

· Keyed insertion to avoid incorrect attachment.

APPLICATIONS

· Telecommunications base stations.

· Servers.

· Handheld data collection equipment.
