Apparatus and method for electronic circuit protection

An apparatus for providing transient protection, the apparatus comprising:

• a detector configured to detect a presence of a transient signal at a first node, wherein the detector is configured to activate a detected state of a detection signal upon detection of the transient signal;
• a timer configured to activate a control signal for a first duration of time based at least partly on a state of the detection signal;
• a current source configured to modify a trigger current at least partly in response to a state of the control signal, wherein the trigger current can be modified to at least two different current levels;
• and
• a latch having a low-impedance state and a high-impedance state, wherein the latch is configured to receive the trigger current as an input, wherein the latch is configured to conduct a latch current from the first node to a second node when the latch is in the low-impedance state, and wherein the latch is further configured to transition from the high-impedance state to the low-impedance state for a first activation voltage of the transient signal when the trigger current is at a first current level and to transition from the high-impedance state to the low-impedance state for a second activation voltage of the transient signal when the trigger current is at a second current level having a magnitude greater than the first current level, and wherein the first activation voltage is greater than the second activation voltage.
