  • Overvoltage transient protection for low side circuits
    Patent number: 6975493
    Abstract: A low side overvoltage protection circuit configuration comprising: a first switching device in operable communication with and disposed between a ground and a protected ground; a load in operable communication with and disposed between a voltage source and the protected ground; a control circuit configured to control the first switching device in operable communication with a transient protected voltage source. The first switching device is configured to provide electrical circuit isolation of the protected ground from the ground. Also, a method for providing a low side circuit overvoltage protection comprising: detecting an overvoltage transient on a voltage source; isolating a protected ground from a circuit ground with a first switching device; and controlling the first switching device with a control circuit in operable communication with transient protected voltage source. The control circuit is responsive to an overvoltage transient of the voltage source.

  • High side reverse and overvoltage transient protection
    Patent number: 6922322
    Abstract: A high side reverse voltage and overvoltage protection circuit configuration comprising: a first switching device in operable communication with a transient protected voltage source; a second switching device in operable communication and in series with the first switching device and in operable communication with an unprotected voltage source; a control circuit configured to control the first switching device and the second switching device in operable communication with another transient protected voltage source. The first switching device is configured to provide reverse voltage protection for the transient protected voltage source; and the second switching device is configured to provide overvoltage protection for the transient protected voltage source.
