SEMICONDUCTOR CIRCUIT

摘要

A semiconductor circuit includes a clamp circuit and a switch circuit connected in series between a first power source terminal and a second power source terminal. The clamp circuit is configured to connect the first power source terminal to the second power source terminal when a voltage difference between the first and second power source terminals exceeds a threshold value. A control circuit controls the switch circuit such that the switch circuit is not conductive (open) when the voltage difference between the power source terminals is constant and is conductive (closed) when the voltage difference between the first and second power source terminals changes by more than a predetermined magnitude.
