Abstract
A half-bridge circuit package structure includes a chip pad, a first metal island, a driving chip, an upper bridge switch, and a lower bridge switch. The driving chip includes a ground pad and a high side ground pad. The upper bridge switch includes a first enhancement mode transistor and a first depletion mode transistor. A drain pad of the first depletion mode transistor is electrically connected to the first metal island. The lower bridge switch includes a second enhancement mode transistor and a second depletion mode transistor. A source pad of the second depletion mode transistor is electrically connected to a drain pad of the second enhancement mode transistor. A drain pad of the second depletion mode transistor is electrically connected to the first metal island.
