Abstract

The power control device reliably disconnects the current path of the failed output transistor. In particular, the power control device includes output transistors, an output terminal, bonding wires connecting the output transistors to the output terminal, output transistor driving circuits controlling the output of the output transistors, and a failure detection circuit detecting the failure of the output transistors. When the failure detection circuit detects the failure of the output transistors and outputs the failure detection signals, the output transistor drive circuits control the outputs of the output transistors so that a larger current flows through the bonding wires than when the failure is not detected.
