Abstract
A device includes a protected terminal, a reference terminal, and a rate-triggered circuit coupled to the protected terminal and to the reference terminal. The rate-triggered circuit is configured to provide an output voltage responsive to a ramp rate of a voltage at the protected terminal being greater than a rate threshold. The device also includes a transistor configured to shunt current from the protected terminal to the reference terminal responsive to the rate-triggered circuit output voltage, and a level-sensing circuit configured to turn off the transistor responsive to the voltage at the protected terminal being greater than a level-sense threshold.
