  • Patent number: 9917581
    Abstract: An electronic device comprising a first power switch connectable or connected between a first voltage source and a load is proposed. The first power switch assumes a conductive state in response to a power-on request and a non-conductive state in response to a power-off request, for energizing and deenergizing the load, so that a voltage across the first power switch tends to a positive high level when the first power switch is in the non-conductive state and to a positive low level when the first power switch is in the conductive state. The device further comprises a second power switch connectable or connected between a second voltage source and the load. The second power switch assumes a conductive state in response to the power-on request and a non-conductive state when the voltage across the first power switch is below a defined switch-off threshold lower than the high level. The second voltage source thus assists the first voltage source in powering up the load.

    Abstract: Aspects of the disclosure are directed to communications between respective power domains (circuitry) that may operate in a stacked arrangement in which the each domain operates over a different voltage range. A first circuit provides differential outputs that vary between first and second voltage levels, based on transitions of an input signal received from a first one of the power domains. First and second driver circuits are respectively coupled to the first and second differential outputs. A third driver circuit operates with the first and second circuits to level-shift the input signal from the first power domain to an output signal on a second power domain by driving an output circuit at the second voltage level in response to the input signal being at the first voltage level, and driving the output circuit at a third voltage level in response to the input signal being at the second voltage level.
