Abstract
An embodiment of an apparatus, such as a circuit breaker, includes an input node, an output node, and a digital circuit. The input node is configured to receive an input voltage, and the output node is coupled to the input node and is configured to carry an output current. And the digital circuit is configured to uncouple the output node from the input node in response to a power drawn from the input node exceeding a threshold.

1-6. (canceled)
An apparatus, comprising:
- an input node configured to receive an input voltage;
- an output node coupled to the input node and configured to carry an output current;
- and
- a digital circuit configured to uncouple the output node from the input node in response to a product of the input voltage and the output current exceeding a threshold.

A system, comprising:
- a load;
- and
- a circuit breaker, including
- an input node configured to receive an input voltage;
- an output node coupled to the input node and configured to provide an output current to the load;
- and
- a digital circuit configured to uncouple the output node from the input node in response to a product of the input voltage and the output current exceeding a threshold.
4 more elements
A method, comprising:
- providing power from a power source to a load with a circuit breaker that includes digital circuitry;
- and
- opening the circuit breaker in response to the digital circuitry determining that a power drawn from the power source exceeds a threshold.
An apparatus, comprising:
- an input node configured to receive an input power;
- an output node configure to provide an output power;
- and
- a digital circuit configured to uncouple the output node from the input node in response to a power that is less than or equal to the input power exceeding a threshold.
