BQ48SH-28X6NSH FEATURES

BQ48SH-28X6NSH DESCRIPTION

The bq48SH–28x6 is the top section suitable for anySOIC (DSH) packaged IC including the bq4802YDSHor bq4802LYDSH parallel real-time clock (RTC) andNVSRAM controller.The fully integrated SNAPHAT includes a 6-pF watchcrystal and lithium coin cell with 48 mAh of capacity.The SNAPHAT is designed to be attached after theDSH packaged base SOIC has been solderedpreventing the battery and crystal being over-stressedby the soldering temperatures.CONNECTION DIAGRAMS

BQ48SH-28X6NSH APPLICATIONS

BQ48SH-28X6NSH functional description

connectionsThe SOIC (DSH) is connected to the SNAPHAT containing the battery and crystal through four pins that insertinto four press-fitted sockets in the SOIC (DSH) where the contact area is gold platted. Each of the socketsinternally contains six independent contacts to ensure solid reliable connectivity and minimize contactresistance.Four molded retaining clips on the SNAPHAT also help fasten the SOIC (DSH), ensuring mechanical andelectrical connection even under severe mechanical shock and vibration. The combined SOIC (DSH) andSNAPHAT assembly can sustain shock levels in excess of 100 g without separating. This package also passesvariable frequency testing in accordance with MIL–STD–883, method 2007.2, condition A.Figure 1 illustrates the effect of repeated insertion and extraction of the SNAPHAT top to the SOIC (DSH). Theforce required to extract the SNAPHAT, and then to re-insert it, reduces each time. After three or fourextractions, though, the reduction starts to become unnoticeable, and the force required remains at a fairlyconstant figure. Typically, though, the SNAPHAT needs to be extracted and re-inserted only once in its lifetime.Figure 1. SNAPHAT Insertion and Extraction Forces
