20130043941 | CURRENT-SENSING CIRCUIT - 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. | 02-21-2013 |
20140097686 | LOW/HIGH VOLTAGE SELECTOR - A voltage selector circuit is described. The voltage selector circuit includes a first voltage input, a second voltage input, and a voltage comparison input. The voltage selector circuit also includes a first voltage selector connected to an output. The first voltage selector is configured to compare the first voltage input and the second voltage input to the voltage comparison input. The voltage selector circuit also includes a second voltage selector connected to the output. The second voltage selector is configured to compare the first voltage input to the second voltage input using an early trigger, such that the second voltage selector is configured to switch on before the first voltage selector switches off. | 04-10-2014 |
