Abstract
A method of determining power fault information using a voltage regulator-down (VRD) device having a fault-pin output. The method may include receiving a fault indication from one of a plurality of fault detection devices, correlating the received fault indication with a timing signal having a predetermined time duration, applying a voltage change on the fault-pin output of the VRD device for the predetermined time duration corresponding to the timing signal, and applying the voltage change on the fault-pin output to a plurality of fuses. Based on the predetermined time duration associated with the applied voltage change, the plurality of fuses may be blown according to a binary pattern indicative of a fault type associated with the fault indication.
