Abstract
Embodiments of methods, apparatuses, devices and systems associated with a power management system are disclosed.
Claims52
A power management system comprising:
- a state machine, capable of transitioning the power management system to a safe state when an input signal and/or an output signal from a component of the power management system indicates occurrence of an error in the component.
An apparatus comprising:
- an integrated circuit, said integrated circuit including a plurality of circuit components and a power management state machine, said power management state machine comprising circuitry to implement a set of state conditions corresponding to a set of defined input signals and/or output signals of the plurality of circuit components.
A system comprising:
- a startup circuit component operable to generate a startup signal in response to an external event applying a voltage to the startup circuit component;
- and
- a supervisor circuit component operable to initiate a startup sequence of an integrated circuit in response to the startup signal.
An apparatus comprising:
- a power management means for allowing a circuit to operate in a plurality of power consumption modes;
- and
- a state management means for transitioning said circuit between said plurality of power consumption modes.
A method comprising:
- enabling a charge pump if an output signal of a controller exceeds a first threshold level;
- enabling a voltage regulator if an output signal of the charge pump exceeds a second threshold level;
- and.
- entering a power on state when no error has occurred during the enabling.
1 more element
An article comprising:
- a storage media having stored thereon instructions that when executed result in:
- enabling a charge pump if an output signal of a controller exceeds a first threshold level;
- enabling a voltage regulator if an output signal of the charge pump exceeds a second threshold level;
- and.
- entering a power on state when no error has occurred during the enabling operation.
