ABSTRACT:
The present invention provides a general purpose driver circuit. The driver circuit is connected to a load. The driver circuit includes a controller for producing a control signal indicative of a desired output current. The driver circuit generates an output current having a magnitude responsive to the magnitude of the control signal. The driver circuit produces a system voltage feedback signal and an output voltage feedback signal and responsively performs output load condition diagnostics.
