Claim Text:
1. A circuit comprising: a normally-off transistor; a normally-on transistor comprising a second load path terminal coupled to a first load path terminal of the normally-off transistor, and a control terminal coupled to a second load path terminal of the normally-off transistor; and a driver circuit comprising an output coupled to a control terminal of the normally-off transistor, a first power supply terminal configured to be coupled to a first power supply terminal of a first power supply, and a second power supply terminal configured to be coupled to a second power supply terminal of a second power supply, wherein the second load path terminal of the normally-on transistor is further configured to be coupled to a second power supply terminal of the first power supply and to a first power supply terminal of the second power supply via a circuit path separate from a load path of the normally-off transistor.
