1. Load driver circuit comprising:

  • first comparator means for receiving a load current signal indicative of current flowing through a load and for providing as an output signal a set on signal in response to said load current signal being less than a first threshold;

    second comparator means for receiving said load current signal and providing as an output rignal a set off signal in response to said load current exceeding a second threshold more than said first threshold;

    driver means coupled to said first and second comparator means for receiving said set on signal and said set off signal and providing a load current control signal for controlling current flow through said load in response thereto;

    wherein the improvement comprises means for disabling at least one of said first and second comparator means in response to and after said one of said first and second comparator means provides its output signal, whereby the generation of undesired set on/set off signals due to noise signals is minimized.
