Abstract:
1. An apparatus for providing transient electrical event protection, the apparatus comprising: a detection and timing circuit configured to detect a presence or absence of a transient electrical event at a first node, wherein the detection and timing circuit is further configured to generate a first current for a first duration upon detection of the transient electrical event; a current amplification circuit configured to receive the first current from the detection and timing circuit and to amplify the first current to generate a second current, the current amplification circuit comprising; a clamping circuit electrically connected between the first node and the second node and configured to receive the second current for activation, wherein the clamping circuit is configured to activate a low impedance path between the first and second nodes in response to the second current, and to otherwise deactivate the low impedance path.
