Abstract
A circuit device connected between a neighboring pair of terminals in a semiconductor integrated circuit is protected from electrostatic damage due to a surge voltage when the surge voltage is applied between the neighboring pair of terminals. The semiconductor integrated circuit is formed to include terminals P-P, MOS transistors MN-MNin diode connection, protection diode circuits HD-HD, MOS transistors T-Tfor discharging electricity from batteries, a battery voltage detection control circuit and a clamp circuit for overvoltage protection. Each of the MOS transistors T-Tfor discharging electricity from the batteries is connected between each neighboring pair of the terminals P-Pthrough wirings. Each of the MOS transistors MN-MNin diode connection is connected between each neighboring pair of the terminals.
