Abstract
A driver circuit suitable for use to secure output characteristics higher than the element breakdown voltage in an output circuit. The driver circuit includes first and second switching elements connected between a first supply voltage and an outward terminal for driving a load, a relaxation voltage applying section for applying a voltage lower than the first supply voltage to a junction point between the first and second switching elements and a back gate of the second switching element, and a control section for turning on the second switching element and then the first switching element in sequence when the driver circuit is turned on, and turning off the first switching element and then the second switching element in sequence when the driver circuit is turned off.
