Abstract
In a motor control circuit, a switching element such as an FET for controlling a motor current and a current detection element for detecting the motor current are connected in series. One terminal of a temperature detection element is electrically connected to an electrical connecting section between the FET and the current detection element, and the other terminal of the temperature detection element is electrically connected to a temperature detection circuit.
