Abstract
A semiconductor component that includes a current limit circuit and a method for limiting current in the semiconductor component. An input/output pin is connected to the gate of a transistor and a control resistor is connected between the gate of the transistor and its source. One terminal of the control resistor is connected to the input/output pin and the other terminal is connected to another input/output pin. A current source is connected to the input/output pin. A reference voltage is generated between the two input/output pins and compared with a drain-source voltage that is between one of the two input/output pins and another input/output pin. A control voltage is set in accordance with the comparison. The control voltage then controls the voltage on another of the pins that is not common to the reference voltage and to the drain-source voltage.
