摘要:
Embodiments of the present invention relate to an improved die layout for a bi-directional and reverse blocking battery switch. According to one embodiment, two switches are oriented side-by-side, rather than end-to-end, in a die package. This configuration reduces the total switch resistance for a given die area, often reducing the resistance enough to avoid the use of backmetal in order to meet resistance specifications. Elimination of backmetal reduces the overall cost of the die package and removes the potential failure modes associated with the manufacture of backmetal. Embodiments of the present invention may also allow for more pin connections and an increased pin pitch. This results in redundant connections for higher current connections, thereby reducing electrical and thermal resistance and minimizing the costs of manufacture or implementation of the die package.
