| Zusammenfassung: | An overcurrent sensing apparatus comprises current sensing circuitry configured to generate an analog output signal representative of a sensed current; an analog to digital converter configured to receive the analog output signal and generate a digital representation of the analog output signal using a plurality of discrete samples, wherein each of the plurality of discrete samples representative of the analog output signal substantially at or above a maximum current value has a substantially identical magnitude; and a controller configured to estimate an amount of an overcurrent sensed by the current sensing circuitry by evaluating the samples having the substantially identical magnitude. |
