Abstract
One example discloses a bridge controller, including: a slope detector coupled between the first input node and the second output node; wherein the slope detector is configured to measure a rate of change of an input voltage across the first input node and the second input node; and wherein the bridge controller is configured to blank at least one of the first switch and the second switch if the measured rate of change exceeds a predetermined value.
