Abstract
An integrated battery package, that contains semiconductor chips, for example to control and regulate battery charging and to monitor the package operation, uses a single lead frame to interconnect several internal chips, to internally connect said control chips to the battery and to connect the whole package assembly externally. The invention eliminates the need for any additional connecting mechanism. The invention uses established production processes. A molding process, similar to plastic chip encapsulation, encloses the battery controlling chips and forms at the same time the body of the battery package. An additional cover, sealed to said body, closes the battery package.
