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.
