Abstract

In certain aspects, a clamp includes first and second transistors coupled in series between a power bus and a ground. The clamp also includes a resistive voltage divider configured to bias a gate of the first transistor and a gate of the second transistor based on a supply voltage on the power bus. The clamp further includes a capacitive voltage divider configured to turn on the first and second transistors in response to a voltage transient on the power bus exceeding a trigger threshold voltage.
