Abstract
A data storage device includes a power supply circuit configured to supply power to the data storage device. The power supply circuit includes a voltage clamp configured to operate in a conduction state in response to an over-voltage condition of the power supply circuit. The power supply circuit also includes a fuse in series with the voltage clamp. The fuse is configured to open in response to a current flow through the fuse and the voltage clamp exceeding a threshold value. The power supply circuit also includes a switching device that is configured to latch in a forward conduction mode in response to the voltage clamp operating in the conduction state. The switching device couples power from a positive voltage bus to the voltage clamp when the switching device is in the forward conduction mode.
