Patent Images
1. A bi-directional transistor comprising:
- a first MOS transistor having a body region, a first current carrying electrode, and a second current carrying electrode;
a switch configured to selectively couple the body region of the first MOS transistor to the first current carrying electrode or the second current carrying electrode of the first MOS transistor responsively to signals applied to the first current carrying electrode and the second current carrying electrode of the first MOS transistor; and
a second MOS transistor configured to selectively form a current flow path in parallel with the first MOS transistor.
