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 lithium coin cell with 48 mAh of capacity.
The SNAPHAT is designed to be attached after the
DSH packaged base SOIC has been soldered
preventing the battery and crystal being over-stressed
by the soldering temperatures.
