Abstract:
Apparatus and methods for active detection, timing, and protection related to transient electrical events are disclosed. A detection circuit generates a detection signal in response to a transient electrical stress. First and second driver circuits of an integrated circuit, each driver having one or more bipolar junction transistors, activate based on the detection signal and generate activation signals. The one or more bipolar junction transistors of the first and second driver circuits are configured to conduct current substantially laterally across respective base regions. A discharge circuit, having an upper discharge element and a lower discharge element, receives the activation signals and activates to attenuate the transient electrical event.
