Abstract
A driving circuit is placed on an IC chip, and which drives a semiconductor switching element. The driving circuit includes: a power supply circuit for receiving a first voltage supplied from a single power supply provided outside the IC chip, generating a second voltage based on the first voltage, and applying the second voltage to a reference terminal of the semiconductor switching element; and a driving part for driving the semiconductor switching element by applying the first voltage or stopping application of the first voltage to a control terminal of the semiconductor switching element in response to an input signal given from outside the IC chip.
