Abstract
An implementation of a system disclosed herein provides a method comprising detecting a power loss to an apparatus, isolating the apparatus from a power supply, notifying the apparatus of the power loss, and extending operation of the apparatus for a predetermined time period using a charge reservoir.
Claims20
A method comprising:
- detecting a power loss to an apparatus;
- isolating the apparatus from a power supply using a pFET circuit;
- and
- notifying the apparatus about the power loss.
1 more element
A device, comprising:
- a detector configured to detect a power loss to an apparatus by detecting a negative AC event at an input terminal;
- an isolator circuit configured to isolate the apparatus from a power supply;
- a flag generator configured to generate a flag in response to the power loss;
- and
- a sustain circuit configured to sustain operation of the apparatus for a predetermined time period.
2 more elements
A storage device, comprising:
- a disc drive circuit configured to operate the storage device;
- a host interface configured to provide power to the disc drive circuit;
- and
- a power loss mitigation circuit configured to detect a power loss at the host interface, and in response to detecting the power loss using a decline in the DC power at the host interface below a reference level and isolating the disc drive circuit from the host interface.
