Elektronischer Schalter mit Überstrom-Schutzvorrichtung

摘要

The invention relates to an electronic switch which is based on a semiconductor and which comprises a current protection device that protects against excess current. The protective device comprises a magnetic field sensor which is located on a current-carrying conductor (7) and which measures the flow of current. A body (8), which is made of a material having a magnetic permeability that is significantly greater than 1, is arranged together with the magnetic field sensor in order to increase the sensitivity of the sensor and to reduce the dependency thereof on current non-homogeneities.
