  • Patent number: 11448670
    Abstract: Apparatus and associated methods relate to detection of an overcurrent condition by determining if a voltage across a current-sense resistor exceeds a predetermined voltage threshold. The voltage at each side of the current-sense resistor is sensed indirectly, through a diode network. The diode networks through which the voltages on each side of the current-sense resistor are biased differently from one another. Such differently-biased diode networks translate the voltages at each side of the current-sense resistor by different amounts, the biasing of these diode networks is such that a voltage difference between the second terminals of the first and second diode networks is of a first polarity during normal current conditions, and the voltage difference between the second terminals of the first and second diode networks is of a second polarity during overcurrent conditions.
