<p>A system provides overload protection in power-switching circuitry, whereby current through a switch is controlled by adaptive circuitry. The switch, configured to deliver a current and a voltage, is connected to two current-limiting feedback circuits. The first current-limiting feedback circuit is coupled to the switch and limits the current through the switch based on current measured through the switch. The second current-limiting feedback circuit is configured to shunt current around the first current-limiting feedback circuit as a function of the voltage delivered to the load, which changes the amount of current the switch can deliver to the load.</p> |
