<p>Apparatus and methods for providing transient electrical event protection are disclosed. In one embodiment, an apparatus (10) comprises a detection and timing circuit (21), a current amplification circuit (22), and a clamping circuit (23). The detection and timing circuit is configured to detect a presence or absence of a transient electrical event (14) at a first node, and to generate a first current for a first duration upon detection of the transient electrical event. The current amplification circuit is configured to receive the first current from the detection and timing circuit and to amplify the first current to generate a second current. The clamping circuit is electrically connected between the first node and a second node and receives the second current for activation. 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.</p> |
