Abstract
An electronic device having first and second terminals includes an electrical overstress (EOS) protection circuitry configured to detect an EOS event at one or both of the first and second terminals. The electronic device includes a power clamp coupled to the EOS protection circuitry and configured to clamp a voltage between the first terminal and the second terminal to a clamp voltage. The EOS protection circuitry can adjust the clamp voltage when an EOS event is detected.
