Classification: CPC G  H | IPC G  H

Claim 13:
14. A data storage device, comprising:
a power supply circuit, including:
a voltage clamp configured to operate in a conduction state in response to an over-voltage condition of the power supply circuit;
a fuse in series with the voltage clamp and the positive voltage bus, wherein the fuse is configured to open in response to a current flowing through the fuse and the voltage clamp exceeding a threshold value;
a switching device configured to latch in a forward conduction mode in response to the voltage clamp operating in the conduction state, wherein the switching device couples a positive voltage bus to the voltage clamp when operating in the forward conduction mode; and
an over-voltage detection circuit configured to detect an occurrence of an over-voltage event.
