Claim:
1. A circuit apparatus comprising: an output circuit that includes a high-side transistor and a low-side transistor; a control circuit that performs control so as to turn on and off the high-side transistor and the low-side transistor; and a driver circuit that drives the high-side transistor and the low-side transistor based on a control signal from the control circuit, wherein at least one of the high-side transistor and the low-side transistor is constituted by first to n-th transistors that are connected in parallel, and the circuit apparatus further includes first to n-th pads, each connected to a drain of a corresponding one of the first to n-th transistors and used to detect a fault in the at least one transistor, the first to n-th pads are configured to contact a probe that is pressed against the first to n-th pads to perform an inspection to detect the fault.
