Abstract

See full text

This application discusses, among other things, protection methods and apparatus for integrated circuits. In an example, an apparatus to protect a circuit from transient electrical events can include a protection transistor configured to couple a terminal of the circuit to a reference potential during the transient events, and one or more diodes coupled in series between the terminal and a control node of the protection transistor, the one or more diodes configured to trigger the protection transistor at a predetermined voltage of the terminal. In some examples, the apparatus does not include a clamp diode coupled between the control node of the protection transistor and the reference potential.
