A method of over-current protection includes: determining a current flowing through a first element to be protected, comparing the determined current with a plurality of thresholds, controlling a counter based on the comparing the determined current with a plurality of thresholds, and stopping the current flowing through the first element by activating a switch in series with the first element when an output of the counter reaches a predetermined counter threshold.

Circuit and method of over-current protection

Devices and methods are provided relating to supplying a load having an inrush-current behavior, e.g. charging of a capacitance e.g. at power up of a circuit. A first load path and a second load path are provided which are used in an alternating manner.

Supplying load having inrush-current behaviour

A device is suggested comprising at least two transistors, each of the transistors comprising a current path and a control terminal, wherein the current paths of the at least two transistors are arranged in parallel, wherein the control terminals of the at least two transistors are connected to a control node via at least one voltage drop component. Also, a method to efficiently control at least two transistors is provided.

Controlling at least two transistors

Disclosed is a method and a drive circuit. The method includes measuring a frequency of an input signal received by a drive circuit and driving a transistor device by the drive circuit based on the input signal such that a switching speed of the transistor is dependent on the measured frequency. The drive circuit is configured to receive an input signal, to measure a frequency of the input signal, and to drive a transistor device based on the input signal such that a switching speed of the transistor is dependent on the measured frequency.
