Semiconductor integrated circuit device having an ESD protection unit

摘要

A semiconductor integrated circuit device includes a semiconductor integrated circuit formed in a semiconductor chip, and a switching element that is formed in the semiconductor chip and has a current path whose one end and the other end are both connected to the semiconductor integrated circuit. The switching element receives a control signal produced by a control circuit and causes a current to flow from the one end to the other end of the current path by a bipolar operation. The semiconductor integrated circuit device further includes the control circuit that is formed in the semiconductor chip and configured to control a conductive/non-conductive state of the current path of the switching element.
