A circuit assembly for discharging an electrical energy store includes a first discharge current path for uncontrolled, passive discharging of the energy store and for keeping a defined charge voltage of the energy store, and a second discharge current path for controlled, active discharging of the energy store. A semiconductor switch electrically connects to a positive current connection of the energy store and to a negative current connection of the energy store. A voltage limiter includes a first current connection for electrically connecting to the positive current connection of the energy store and a second current connection for electrically connecting to the negative current connection of the energy store. The circuit assembly further includes a first control path for providing a first control signal from the first current connection of the voltage limiter to the control connection of the semiconductor switch in order to control the semiconductor switch.

Circuit arrangement for discharging an electrical energy store and power converter comprising such a circuit arrangement

A surface-mountable magnetic field sensor () with a semiconductor chip (), a magnetic field measuring device (), and in a method for producing and populating a circuit board () having a magnetic field sensor (), the magnetic field sensor () has a semiconductor chip (), which is arranged on a flat-conductor substrate (). At least three flat-conductor electrodes (to), which protrude out of a plastic housing side (), are electrically connected to the semiconductor chip (). The flat-conductor substrate () and the semiconductor chip () are embedded in a plastic housing (). The plastic housing () can be inserted with the embedded semiconductor chip () into a magnetic field gap (), with the flat-conductor electrodes (to) protruding, wherein the flat-conductor electrodes (to) have bends (to) at a distance from the plastic housing side (), the bends being surface-mountable on a circuit board.
