Data storage device power monitoring

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;
• 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, and a first system-on-a-chip (“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,
• 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, and
• 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.
