Abstract
In order to suppress a negative influence on a circuit operation caused by variation in a substrate potential, a circuit device includes a bridge circuit having a high-side transistor and a low-side transistor, a detection circuit configured to detect current flowing in the bridge circuit, a control circuit configured to control switching on and off of the bridge circuit, and a guard region for setting a substrate PSB of the circuit device to a substrate potential.
