  • Patent number: 10048735
    Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, an energy storage device such as a capacitive storage circuit is powered relative to the powering of one or more additional circuits from a common power supply to limit the draw upon the power supply. Certain applications involve delaying or otherwise modifying the powering of the capacitive storage circuit, which may involve an initial startup of the capacitive storage circuit.

  • Patent number: 8479032
    Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a data-storage device is implemented having a memory control circuit controlling nonvolatile and volatile memory. An operating power circuit carries primary-operating power from the host-system to the memories and control circuitry. A backup power circuit includes energy-storage circuitry with one or more energy storage devices. An isolation-regulation circuit provides voltage regulation of power from the host-system and also isolates the host-system provided power from the energy storage devices. A regulation power circuit carries the regulated power from the isolation-regulation circuit to the energy storage devices.

  • Patent number: 8065562
    Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a capacitive storage circuit is operated at a threshold voltage that is set to provide sufficient power to operate backup functions of a data storage device, and that is further selectively adjusted during a test period to maintain such sufficient power while also providing power to carry out test functions. In other implementations, the threshold voltage is set in response to operating characteristics of one or more of a data storage device to which backup power is to be provided and the capacitive storage circuit itself. The threshold voltage is reduced or otherwise maintained at a low level that is yet sufficient to supply appropriate power (e.g., thus maintaining the capacitive circuit at a voltage level that is about as low as possible, which can enhance operational characteristics of the capacitive circuit).

  • Patent number: 8009502
    Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, an energy storage circuit is powered using a variable voltage controlled to limit the current draw from a power supply, to charge the energy storage circuit for providing backup power to a solid state drive (SSD) type of data storage arrangement. Certain applications involve controlling the power draw from the power supply, in response to feedback and/or power drawn from other circuits, as may be applicable to an initial startup of the energy storage circuit and/or the initial startup of a larger system in which the energy storage circuit is employed.
