Abstract
A multiphase voltage regulator device (VRD) includes powerstages coupled in parallel between a power input and a voltage regulator power output, each powerstage including a power output stage and a control circuit connected to the power output stage. The VRD further includes a controller connected with the control circuit of each powerstage and a plurality of current sensors, wherein each current sensor measures the amount of current passing through the power output stage of one of the powerstages. The controller is configured to assert a hard short signal to the control circuit of one or more powerstage in response to the measured amount of current passing through any of the powerstages being greater than a predetermined current threshold. Upon receiving the hard short signal, the control circuit is configured to hold the output power stage of the powerstage in a hard short condition by connecting the power input to ground.
