Semiconductor element driving circuit, semiconductor device driving circuit, and semiconductor device

Abstract

Provided are a semiconductor element driving circuit, a semiconductor device driving circuit, and a semiconductor device that are further miniaturized in a semiconductor device having a plurality of semiconductor elements. A semiconductor element driving circuit according to the present invention includes a plurality of semiconductor elements connected in series in a row between a power electrode and a ground electrode; and current supply control transistors connected in parallel to each of the plurality of semiconductor elements, wherein each of the current supply control transistors functions as a switch that controls the flow of current to the semiconductor elements connected in parallel based on a first external signal; when the current supply control transistor is turned off by the first external signal, current flows to the semiconductor element connected in parallel to the current supply control transistor; and when the current supply control transistor is turned on by the first external signal, the flow of current to the semiconductor element connected in parallel to the current supply control transistor is stopped.
