Abstract
An integrated circuit comprises at least one pin and has at least one resistor connected between a reference voltage and the at least one pin. Current measurement circuitry applies a voltage across the at least one resistor and measures a current at the at least one pin responsive to the applied voltage in a first mode of operation. The measured current enables determination of a current limit set point for the integrated circuit. In a second mode of operation, the at least one resistor comprises a pull up resistor and the at least one pin that is connected to the at least one resistor comprises an open-drain output.
