  • Transistor body control circuit and an integrated circuit
    Patent number: 9443845
    Abstract: An integrated circuit comprises a transistor body control circuit for controlling a body of a bidirectional power transistor. The transistor body control circuit comprises switches connected between a body terminal and a first current terminal, with a control terminal for controlling the current flowing through the switch. The control terminal of the switch is connected to alternating current, AC capacitive voltage divider. The AC capacitive voltage dividers are connected to the control terminals and arranged to control the switches to switch the voltage of the body terminal as a function of the voltage between the first current terminal and the second current terminal. The integrated circuit further comprises a bi-directional power transistor connected to the transistor body control circuit.
