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.
Claims13
A half-bridge circuit, comprising:
- a low-side transistor and a high-side transistor each comprising a load path and a control terminal;
- a high-side chive circuit comprising a level shifter with a level shifter transistor, the side drive circuit being configured to drive the high-side transistor;
- and
- wherein the low-side transistor and the level shifter transistor are integrated in a common semiconductor body,
- wherein the load paths of the high-side transistor and the low-side transistor are connected in series between terminals for a positive supply potential and a negative supply potential or a reference potential,
- wherein a circuit node that is common to the load paths of the high-side transistor and the low-side transistor forms an output of the half-bridge circuit.
