Abstract

A half-bridge circuit includes a low-side transistor and a high-side transistor each having a load path and a control terminal, and a high-side drive circuit having a level shifter with a level shifter transistor. The low-side transistor and the level shifter transistor are integrated in a common semiconductor body.
