DS3802 - Dallas Semiconductor

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 supply. The battery cap is keyed to prevent incorrect attachme.
