Abstract
A data storage device includes an electrical connector configured to receive an input voltage to power electronics of the data storage device. The data storage device further includes a fuse electrically coupled between the electrical connector and the electronics. The fuse is configured to output a signal indicative of current being inputted to the data storage device. The data storage device further includes a controller configured to calculate power based on the input voltage and the signal indicative of the current.
Claims17
A data storage device comprising:
- an electrical connector configured to receive an input voltage to power electronics of the data storage device;
- a fuse electrically coupled between the electrical connector and the electronics and configured to output a signal indicative of current being inputted to the data storage device;
- and
- a power device electrically coupled between the fuse and a controller, the power device comprising an amplifier and configured to manage power distribution to the electronics;
- and
- the controller configured to calculate power based on the input voltage and the signal indicative of the current.
A method comprising:
- receiving, by an electrical connector, an input voltage to power electronics of a data storage device;
- receiving, by a fuse electrically coupled between the electrical connector and the electronics, the input voltage;
- outputting, by the fuse and based on the input voltage received by the fuse, a signal indicative of current being inputted to the data storage device;
- converting, via an analog-to-digital converter electrically coupled between the fuse and the controller, the signal indicative of the current from an analog signal to a digital signal;
- scaling down the digital signal before inputting the digital signal to the controller;
- and
- calculating, by a controller, power based on the input voltage and the signal indicative of the current.
Circuitry comprising:
- an electronic fuse, a first analog-to-digital converter, a first system-on-a-chip (“SOC”), a second analog-to-digital converter, and a second SOC,
- the electronic fuse is configured to:
- receive at least two input voltage signals and output a first analog signal indicative of a first current being inputted to a data storage device from at least one of the at least two input voltage signals, and
- output a second analog signal indicative of second current being inputted to the data storage device from the at least two input voltage signals,
- the first analog-to-digital converter is electrically coupled between the electronic fuse and the first SOC and configured to convert the first signal indicative of the first current from the first analog signal to a first digital signal,
- the first SOC is configured to calculate a first power based on one of the at least two input voltage signals and the first digital signal indicative of the first current,
- the second analog-to-digital converter is electrically coupled between the electronic fuse and the second SOC and configured to convert the second signal indicative of the second current from a second analog signal to a second digital signal, and
- the second SOC is configured to calculate a second power based on one of the at least two input voltage signals and the second digital signal indicative of the second current.
