ABSTRACT:
A monitor system and method are described for sensing voltage changes in a plurality of transistors of a multiphase circuit comprising a sensor connected to each one of the plurality of transistors for measuring a voltage drop across the each one, a difference detector for comparing the voltage drop to a previous voltage drop attributable to the each one of the plurality of transistors, and a driver circuit for controlling a state of the plurality of transistors, wherein the driver circuit deactivates one or more of the plurality of transistors when the voltage drop varies from the previous voltage drop by a predefined amount.
