Abstract

A driving device comprises a first transistor (B), a second transistor (B), and a resistance element. The first transistor (B) has one terminal receiving a pulsed current and a control terminal connected to the one terminal. The second transistor (B) has one terminal connected to at least one load, the other terminal connected to a reference potential together with the other terminal of the first transistor (B), and a control terminal connected to the control terminal of the first transistor (B). The resistance element is connected between the control terminal of the first transistor (B) and the other terminal of the first transistor (B).
