Abstract

An apparatus includes a regulator circuit that generates a voltage in response to an input current being supplied to an input terminal and functional circuitry, powered by the voltage generated by the regulator circuit. The functional circuitry, e.g., an oscillator, generates a signal using the generated voltage, the signal indicative that the current is being supplied to the apparatus. The signal can be provided over an isolation link to provide a control signal for controlling a high voltage driver circuit.
