Abstract
An interface circuit, comprising: I/O circuitry configured to couple one or more first terminals with one or more second terminals; a voltage regulator configured to power the I/O circuitry; a restrictor element that is disposed between the voltage regulator and the I/O circuitry, the restrictor element being disposed on a circuit path that connects the voltage regulator to the I/O circuitry, the restrictor element being configured to open the circuit path and disconnect the voltage regulator from the I/O circuitry when an electrical current that is being supplied to the I/O circuitry exceeds a threshold; and a voltage suppressor that is disposed on the circuit path that connects the voltage regulator to the I/O circuitry, the voltage suppressor being disposed between the restrictor element and the I/O circuitry, the voltage suppressor being configured to limit, to a first voltage value, a voltage that is input into the I/O circuitry.
