DS3802 Advanced NV SRAM Battery

The DS3802 battery cap is a snap-on lithium power source for Dallas Semiconductor’s 40mm BGA NV SRAM modules including the DS3832C-311 and DS3816C-511. After a host BGA module has been soldered in place and cleaned, the DS3802 battery cap is snapped onto the module to serve as the secondary power su.
