    nn Available in Thermally Enhanced 12-lead MSOP Package The LTCВ®7860 high efficiency surge stopper protects loads
    from high voltage transients. High efficiency permits
    higher currents and smaller solution sizes. During an
    input overvoltage event, such as a load dump in vehicles,
    the LTC7860 controls the gate of an external MOSFET to ...
