  • Failsafe power oring with current sharing
    Patent number: 6958552
    Abstract: A current sharing circuit provides redundant power supplies with current sharing through the use of multiple feedback loops and existing circuit diodes to generate shared load current within predefined load voltage regulation requirements. A method of sharing current allows adjustment of the feedback loops to accommodate characteristics of the circuit.
    Type: Grant

  • In-rush current protection
    Patent number: 6703889
    Abstract: A circuit for controlling inrush current to a load is provided. The circuit includes a variable impedance device having a control input. The variable impedance device is coupled between a power supply interface and a load interface. The circuit also includes a control circuit coupled to the control input of the variable impedance device and also coupled to the load interface. The control circuit is adapted to provide a signal at the control input of the variable impedance device which results in a linear increase in applied voltage to the load when the circuit is coupled to an input power source. A resistor is coupled between the first and second terminals of the power supply interface to provide a current discharge path for the control circuit when the circuit is disconnected from the power supply.
