Abstract
A method for generating a fault signal in a system voltage regulator by a phase signal includes detecting the system voltage and phase signal; comparing the system voltage and phase signal with respective fault levels; and generating a fault signal upon either the system voltage or the phase signal falling below the respective fault level of the fault levels. The fault signal generating method also inhibits generating a fault signal using a drive signal of the system voltage regulator. A diagnostic circuit for a system voltage regulator is also disclosed.
