Semiconductor integrated circuit

Abstract

A semiconductor integrated circuit includes: one input terminal; multiple output terminals; multiple first current control elements connected between the input terminal and the respective output terminals; a control circuit that controls the first current control elements; a fault detection circuit that includes multiple voltage comparator circuits each of which compares a voltage proportional to a voltage of one of the output terminals with a predetermined threshold voltage and that detects an open-circuit state or a short-circuit state of the output terminals; an external terminal connected to an external resistor; a voltage convertor circuit that generates the threshold voltage according to a voltage of the external terminal that is generated by flowing a current through the external resistor, the threshold voltage being applied to an input terminal of each of the voltage comparator circuits; and a detection result output terminal for outputting a detection result by the fault detection circuit.
