It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesConduction limit protection arrangement for power transistor switch Integrated circuit for controlling power converter by frequency modulation and pulse width modulation Electronic switching device Self-protective fuel pump driver circuit Self protecting and automatic resetting capacitor synchronous switch apparatus for control of AC power to inductive loads Power source apparatus using time sensitive switching Linear voltage regulator compatible with bipolar and MOSFET pass devices and associated methods Patent #: 6005303 InventorAssigneeApplicationNo. 501310 filed on 02/10/2000US Classes:323/282, Switched (e.g., switching regulators)323/283, Digitally controlled361/93.1With specific current responsive fault sensorExaminersPrimary: Berhane, AdolfAttorney, Agent or FirmInternational ClassG05F 001/40Foreign Application Priority Data1999-02-12 JPAbstractAn abnormal current in a first semiconductor switch is detected. When an abnormal current occurs, ON/OFF of the first semiconductor switch is controlled so as to generate a vibration current. The first semiconductor switch is shut off by this vibration current. A voltage between drain and source of the first semiconductor switch is compared with a voltage between drain and source of a second semiconductor switch by means of a comparator. Then, a control voltage is supplied from a driving circuit to gate terminals of the first semiconductor switch and second semiconductor switch according to a result of this comparison.Field of SearchUsing a three or more terminal semiconductive device as the final control deviceFor protective system Switched (e.g., switching regulators) Digitally controlled Using a three or more terminal semiconductive device as the final control device Switched (e.g., switching regulators) With specific current responsive fault sensor Digital control Current limiting | |
