Abstract: A power semiconductor package includes a reference voltage terminal, a supply voltage terminal, a phase terminal, a first power transistor and a second power transistor. The first power transistor and the second power transistor are connected in series and form a low side switch and a high side switch of a half bridge circuit.

Abstract: A rectifying device includes a power transistor, a gate control circuit and a capacitor structure arranged on a single semiconductor die. The power transistor includes a source or emitter terminal connected to a first terminal of the rectifying device, a drain or collector terminal connected to a second terminal of the rectifying device, and a gate. The gate control circuit is operable to control a gate voltage at the gate of the power transistor based on at least one parameter relating to at least one of a voltage and a current between the first terminal and the second terminal.

Abstract: A circuit arrangement includes a first number of loads connected in series. Each of a second number of drive units is coupled to at least one of the first number of loads, and is configured to assume a first operation state or a second operation state. A current source circuit is coupled in series with the first number of loads and is configured to control a load current.
