Abstract

Die Erfindung betrifft einen elektronischen Schaltkreis zum Bereitstellen einer Versorgungsspannung für einen elektronischen Verbraucher. Um die Versorgungsspannung sowohl aus einer externen an den elektronischen Schaltkreis angelegten Spannung wie auch aus einer in dem elektronischen Schaltkreis vorhandenen internen Spannungsquelle generieren zu können, wird erfindungsgemäß vorgeschlagen, eine zu der internen Spannungsquelle parallel geschaltete Reihenschaltung, umfassend eine Diode (D1) und eine mit ihrem einen Ende an die Kathode der ersten Diode (D1) geschaltete Impedanzeinrichtung, vorzusehen. Der Pluspol (+Vex) der externen Spannungsquelle ist an die Kathode der ersten Diode (D1) und der Minuspol (0V) der externen Spannungsquelle ist an den Minuspol der internen Spannungsquelle angeschlossen. Die Versorgungsspannung wird dann über der Impedanzeinrichtung abgegriffen und aus der externen Spannungsquelle generiert, wenn die externe Spannung größer als die von der internen Spannung generierte interne Spannung zuzüglich der Durchlassspannung der ersten Diode (D1) ist.The invention relates to an electronic circuit for providing a supply voltage for an electronic consumer. In order to be able to generate the supply voltage both from an external voltage applied to the electronic circuit and from an internal voltage source present in the electronic circuit, it is proposed according to the invention to have a series circuit connected in parallel with the internal voltage source, comprising a diode (D1) and one with their one end to the cathode of the first diode (D1) connected impedance means to provide. The positive pole (+ Vex) of the external voltage source is connected to the cathode of the first diode (D1) and the negative pole (0V) of the external voltage source is connected to the negative pole of the internal voltage source. The supply voltage is then tapped across the impedance device and generated from the external voltage source when the external voltage is greater than the internal voltage generated by the internal voltage plus the forward voltage of the first diode (D1).
