Abstract
A method and circuit for protecting circuit elements in a traffic control system from an overcurrent condition. In accordance with an embodiment, the circuit includes a current sensing element, a switching element, and a microcontroller. The circuit monitors first and second operating parameters and compares the first operating parameter with a first reference parameter and the second operating parameter with a second reference parameter. In response to the first operating parameter exceeding the first reference parameter and the second operating parameter exceeding the second reference parameter, the microcontroller generates a control signal to open the switching element.
