PROBLEM TO BE SOLVED: To provide a semiconductor device capable of continuing supply of constant current even during overcurrent prevention operation.SOLUTION: In an output driver circuit 100, an output PMOS transistor MP11 supplies current to an external load 110 via an output terminal Tout. A detection circuit 11 changes a level of a detection signal SIGd output according to current I2 flowing in the output PMOS transistor MP11. A switching circuit 12 limits the current flowing in the output PMOS transistor MP11 according to the detection signal SIGd. |
