摘要： An integrated full bridge circuit includes four transistors divided into two series-connected pairs of transistors each forming a half bridge circuit. Resistor elements each connect a respective one of the pairs of transistors to a reference potential. Other resistor elements are each connected to a respective one of two separate supply terminals inside a housing. Each of the other resistor elements is connected to one of the transistors of a respective one of the pairs of transistors at a junction. Driver transistors each have a load path with two connections and a type complementary to the transistors connected to the other resistor elements. One of the connections is connected upstream of the control terminal of a respective one of the transistors connected to the other resistor elements. The other of the connections in each of the half bridge circuits is connected to the junction in the other of the half bridge circuits. The advantage is power loss reduction.

摘要： A circuit for controlling the switching operation of a transistor is described. A gate driver circuit is operably connected to a control electrode of the transistor and is configured to charge and discharge the control electrode to switch the transistor on and off, respectively, in accordance with a control signal. The charging and discharging of the control electrode is done such that the corresponding transitions in the load current and the output voltage are smooth with a defined slope. A controllable switch is connected to the control electrode such that, when the switch closes, the control electrode is quickly discharged via the switch thus quickly switching off the transistor. A control logic circuit is configured to close the controllable switch for switching off the transistor when at least one of a number of conditions holds true.

A switching signal is applied at an input terminal of the driver circuit and an output terminal that is connected to a control input of the semiconductor switch outputs a drive signal.

摘要： A power switching circuit with reduced interference radiation includes at least one pair of low-side and high-side MOS power transistors, between which a load resistor is connected. One or at least one of the low-side MOS power transistors is connected to a drive circuit having a divider for dividing a difference between a maximum output voltage of the MOS power transistor and an instantaneous output voltage at the load resistor as a dividend, by a maximum output voltage of the MOS power transistor as a divisor, and a level converter for generating a drive voltage for the MOS power transistor. The drive voltage is proportional to the quotient.
