Abstract
A power stage in an electronic fuse circuit is driven by controller. The controller includes a first comparator set for output voltage control and a second comparator set for output current control. Each comparator set includes at least one comparator having a reference input, a feedback input, and one or more outputs. A driver circuit includes output terminals for driving the power stage. The driver circuit includes a switch that is selectively activated in response to outputs from the first and second comparator sets to clamp the voltage across the output terminals of the driver circuit. The clamp operation is made in response to feedback input to either of the first and second comparator sets having exceeded a certain reference.
