Abstract
In an embodiment, a semiconductor device is disclosed that includes a bidirectional unipolar-bipolar DC-DC circuit. The bidirectional unipolar-bipolar DC-DC circuit includes a first transistor, a second transistor, a third transistor and a fourth transistor. The first transistor is connected between a reference ground connection and a first connection of a coil. The second transistor is connected between a positive bipolar input/output connection and the first connection of the coil. The third transistor is connected between a second connection of the coil and a negative bipolar input/output connection. The fourth transistor is connected between the second connection of the coil and a unipolar voltage input/output connection. The bidirectional DC-DC circuit is configured to concurrently activate the second and third transistors to cause a current flow through the coil between the positive bipolar input/output connection and the negative bipolar input/output connection.
