nn Available in Thermally Enhanced 12-lead MSOP Package The LTC®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 …
