  • Patent number: 9287875
    Abstract: Circuits and methods for controlling electrical coupling by a load switch are disclosed. In an embodiment, the load switch includes a pass element, level-shift circuit and low-resistance active path. The pass element is configured to be coupled to a power supply and a load, and is configured to electrically couple the power supply with the load during ON-state and electrically decouple the power supply from the load during OFF-state. The level-shift circuit includes a first transistor and pull-up resistor and is configured to generate a level-shifted signal in response to an enable signal, and enable the ON-state and the OFF-state of the pass element based on first and second voltages of the level-shifted signal. The low-resistance active path is coupled in parallel with the pull-up resistor for shunting the pull-up resistor in the OFF-state by providing a path for a leakage current of the first transistor in the OFF-state.
