Abstract
A voltage regulator system of an information handling system includes a voltage regulator and a voltage regulator controller. The voltage regulator includes multiple power-stages (Pstages). The voltage regulator controller communicates with the voltage regulator. The voltage regulator controller monitors for a first fault signal on a first pin of a circuit associated with a first Pstage of the Pstages. In response to a first voltage of the first fault signal at the first pin being greater than a threshold voltage, the voltage regulator controller monitors a second pin of the circuit for a second fault signal and determines whether a voltage of the second fault signal at the second pin is equal to a second voltage. Based on the voltage of the second fault signal being equal to the second voltage, the voltage regulator controller determines a first fault has occurred in the first Pstage.
