Abstract: In accordance with an embodiment, a method includes operating a transistor device by a drive circuit in one of a first operating mode and a second operating mode based on an operating mode signal received by the drive circuit. Operating the transistor device in each of the first operating mode and the second operating mode includes switching on the transistor device based on a drive signal received by the drive circuit; monitoring at least one operating parameter of the transistor device; and switching off the transistor device independent of the drive signal when the at least one operating parameter reaches a respective predefined off-threshold. Switching on the transistor device in the second operating mode includes switching on the transistor with a second slew rate that is smaller than a first slew rate in the first operating mode.

Abstract: An embodiment electronic circuit includes an electronic switch comprising a load path, a first protection circuit configured to generate a first protection signal based on a current-time-characteristic of a load current through the load path of the electronic switch, and a drive circuit configured to drive the electronic switch based on the first protection signal. The first protection circuit includes an analog-to-digital converter (ADC) configured to receive an ADC input signal representing the load current, to sample the ADC input signal once in each of a plurality of successive sampling periods, and to output an ADC output signal that includes a sequence of values such that each of the values represents a respective sample of the ADC input signal. The ADC is configured to pseudo-randomly select a sample time in each sampling period.

Abstract: In one example, a method includes determining, by a temperature sensor, a temperature of a device that controls an amount of current flowing to a load, and determining, based on the temperature of the device, a threshold current. The method also includes, in response to determining that the amount of current flowing to the load is greater than the threshold current, adjusting the amount of current flowing to the load.

Abstract: In accordance with one example, the electronic switch has a load current path operably coupled to a load via a wire; the electronic switch is configured to connect or disconnect a load current supply node and the load via the wire dependent on a drive signal. Further, the electronic fuse circuit includes a monitoring circuit configured to receive a current sense signal representing the load current passing through the wire and to determine a first protection signal based on the current sense signal and at least one wire parameter. The first protection signal is indicative of whether to disconnect the load current supply node from the load. Moreover, the electronic fuse circuit includes a logic circuit configured to receive at least one selection signal and to set the at least one wire parameter based on the at least one selection signal.

Abstract: In one example, a circuit includes an input, an output, and a control module. The input is configured to receive a control signal indicating whether to activate or deactivate a load. The output is configured to supply current to activate the load. The control module is configured to determine whether a state of the circuit is a low current consumption mode (LCCM). In response to determining that the state of the circuit is not the LCCM, the control module is configured to determine whether the control signal indicates to activate the load and output, at the output, the current to activate the load. In response to determining that the state of the circuit is the LCCM, the control module is configured to ignore the control signal indicating whether to activate or deactivate the load and output, at the output, the current to activate the load.

Abstract: Methods, devices, systems, and integrated circuits are disclosed for switching on an electrical connection to one or more loads. In one example, a switch device includes a voltage source, a power switch circuit block connected to the voltage source, and a current limitation circuit block connected to the voltage source and the power switch circuit block. The switch device further includes a voltage outlet connected to the power switch circuit block. The switch device further includes a current limit feedback circuit connected to the power switch circuit block and the current limitation circuit block. The current limit feedback circuit is configured to enable the switch device to provide a regulated connection between the power switch circuit block and the voltage outlet, wherein the regulated connection defines a current limitation mode, such that the regulated connection reduces the current in the power switch circuit block if the switch device is in the current limitation mode.
