Patent number: 10779382Abstract: A semiconductor device for outputting a control parameter includes a receiving unit, a storage unit and an output unit. The semiconductor device also contains antenna connections, supply connections and at least one output connection for outputting a control parameter signal. The receiving unit contains connections for connection to an antenna, from which the receiving unit receives signals. The receiving unit converts the signals received from the antenna into data. The data are stored in the storage unit. The semiconductor device outputs an output signal at the output connection on the basis of the data stored in the storage unit. The semiconductor device additionally contains a calculation unit which determines the operating hours (time) of the semiconductor device. The output signal depends both on the data stored in the storage unit and on the determined operating hours (time).Type: GrantFiled: October 8, 2019Date of Patent: September 15, 2020Assignee: Infineon Technologies Austria AGInventors: Doris Keitel-Schulz, Matthias Schneider, Qi Zhu, Dieter Zipprick

Patent number: 9083243Abstract: The present invention relates to a protection circuit for protecting a half-bridge circuit. The protection circuit detects an incorrect response of the half-bridge by monitoring the current of a first switch at a series resistor of a second switch. The protection circuit has a detector for detecting the voltage across the resistor and an evaluation circuit which is designed in such a manner that it evaluates an output signal from the detector after the first switch has been switched on and provides a fault signal at an output when the voltage across the resistor is greater than the threshold voltage.Type: GrantFiled: May 13, 2013Date of Patent: July 14, 2015Assignee: INFINEON TECHNOLOGIES AUSTRIA AGInventors: Martin Feldtkeller, Dieter Zipprick

Patent number: 7812612Abstract: For monitoring the operation of a gas discharge lamp operated with an AC voltage, a lamp voltage signal is generated which is dependent on the voltage dropped across the gas discharge lamp during operation. The lamp voltage signal is filtered with an attenuation that is different for a DC component and for a component having the frequency of the AC voltage, whereupon a positive and negative peak value of the filtered lamp voltage signal are determined. For monitoring the gas discharge lamp, an average value of the two peak values is determined and compared with a limit value, and a difference value between the two peak values is determined and compared with a limit value.Type: GrantFiled: September 28, 2007Date of Patent: October 12, 2010Assignee: Infineon Technologies AGInventors: Martin Feldtkeller, Michael Herfurth, Dieter Zipprick
