Abstract: A control circuit for controlling a first transistor includes a diode for suppressing transient voltages. A cathode of the diode is coupled to a first conduction terminal of the first transistor, and an anode of the diode is coupled to a first node. A first resistor is coupled between the first node and a control terminal of the first transistor. A second transistor has a control terminal coupled to the first node, a first conduction terminal configured to receive a first supply voltage, and a second conduction terminal coupled to the control terminal of the first transistor.
