ABSTRACT:
A semiconductor integrated circuit of the present invention has an output field-effect transistor formed on a main surface of a semiconductor substrate; an overcurrent detection circuit detecting an overcurrent of the output field-effect transistor; and an overcurrent limiting circuit which is connected between the gate electrode terminal and the source electrode terminal of the output field-effect transistor, controls the detected current of the overcurrent detection circuit and varies its output voltage according to variation in threshold voltage of the output field-effect transistor.
