Inductive-load control circuit

An inductive-load control circuit comprising:

• a circuit board on or in which a controller and a driving circuit are disposed;
• an inductive load disposed at a location apart from the circuit board and connected to the driving circuit of the circuit board;
• a detection resistor group included in the driving circuit and connected in series with the inductive load;
• and
• a temperature measuring element, wherein
• the detection resistor group includes a plurality of resistors, and the temperature measuring element is disposed between the plurality of resistors,
• the controller and the driving circuit are supplied with electric power by a power supply,
• the driving circuit controls the electric power supplied by the power supply and applies the electric power to the inductive load,
• the circuit board has a signal ground connected to the controller and a power ground connected to the detection resistor group of the driving circuit,
• the temperature measuring element is connected to the power ground,
• the temperature measuring element is connected to a regulated voltage via another resistor, and a value of the regulated voltage is different from a value of the electric power supplied by the power supply, and
• a node connecting between the temperature measuring element and the another resistor is connected to the controller.
