Abstract
A circuit for ground disconnection protection is provided herein. In an embodiment, the circuit includes power transistor elements in a common-source arrangement coupled between a first ground and a second ground. The power transistor elements are configured to turn on during a ground disconnection event in an electric motor system. This allows a current to pass between the first ground and the second ground, bypassing a control circuit.
