DESCRIPTION

The DS3800 Battery Cap is a snap–on lithium power source for Dallas Semiconductors 40mm ball–grid

array (BGA) Nonvolatile SRAM modules. After a host BGA module has been soldered in place and

cleaned, the DS3800 Battery Cap is snapped onto the module to serve as the secondary power supply.

The Battery Cap is keyed to prevent incorrect attachment and is designed to maintain mechanical and

electrical contact with its host module even during severe shock and vibration. Electrically, the DS3800

battery is connected to the host BGA module with gold–plated round pins in the Battery Cap inserted into

gold–plated receptacles on the BGA. Mechanically, four flanges on the DS3800 tightly grip the BGA

module board to prevent Cap removal, while corner features in the Cap prevent lateral movement of the

Cap while it is attached to its host BGA module.
