Classification: CPC G  H | IPC G  H

Claim 8:
9. A method performed by a data storage device having a controller coupled to a non-volatile memory device, the method comprising:
detecting an occurrence of an over-voltage condition, wherein the over-voltage condition is detected by an over-voltage detection circuit;
operating a voltage clamp of the data storage device in a conduction state in response to the occurrence of the over-voltage condition;
latching a switching device of the data storage device 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 of a power supply circuit of the data storage device to the voltage clamp when operating in the forward conduction mode;
receiving an indication of the detected occurrence of the over-voltage condition at the controller;
storing the occurrence of the over-voltage condition in a memory; and
transmitting the occurrence of the over-voltage condition to an external device.
