Abstract

The present invention has an object to provide a semiconductor device that has protective functions and is capable of achieving miniaturization and cost reduction. A semiconductor device according to the present invention includes a switching element, a drive circuit, and a control circuit. When a high-level drive control signal is output from the drive circuit, the control circuit stops driving of the switching element and charges an electric charge storing capacitor. When a low-level drive control signal is output from the drive circuit, the control circuit drives the switching element using electric charges stored in the electric charge storing capacitor.

First claim

The invention claimed is:

1. A semiconductor device comprising:
a switching element;
a drive circuit that outputs, on the basis of a control signal provided from an external control device, a drive control signal for driving said switching element; and
a control circuit that controls driving of said switching element on the basis of said drive control signal output from said drive circuit, wherein
said drive circuit is configured to
output said drive control signal in a low…
