PROBLEM TO BE SOLVED: To reduce a burden on a microcomputer in check of a state of a load and reduce the number of terminals of a semiconductor device while reducing power consumption.SOLUTION: A semiconductor device comprises a drive circuit 14, a standby circuit 11, an input circuit 13, a detection circuit 12 and an output transistor 15. The drive circuit 14 turns on the output transistor 15 connected to a load based on an active input signal. The standby circuit 11 intermittently outputs an output signal based on an inactive input signal. The detection circuit 12 measures a voltage of the output transistor 15 on the side of the load 7 based on the output signal and outputs the measurement result. |
