Abstract
In one embodiment, a circuit is provided. The circuit includes a low-ohmic circuit and a a power supply node configured and arranged for providing a supply voltage across the low-ohmic circuit to a load from which current can be drawn. The circuit also includes a current reference circuit, configured and arranged for setting a current reference level that is based on a portion of the current from the power supply node, and a current-sensing circuit. The current-sensing circuit senses and is responsive to current passing through the low-ohmic circuit. The current-sensing circuit operates in a normal mode, in which the current-sensing circuit senses an amount of current passing through the low ohmic circuit that is less than the current threshold level, and in an over-current mode, in which the current-sensing circuit senses an amount of current passing through the low ohmic circuit that is greater than the current threshold level.
