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.
