Abstract:
An inductive load driving device includes a first switching element, a second switching element, a counter current regeneration circuit, and a circuit element protection circuit. The first switching element is coupled between an output terminal of the power circuit and one end of the inductive load. The second switching element is coupled between the other end of the inductive load and a ground terminal. The counter current regeneration circuit is configured to supply to the output terminal of the power circuit, a counter current output from the other end of the inductive load when the first and second switching elements are in off-state. The circuit element protection circuit is configured to turn on the second switching element when a value of the output voltage of the power circuit becomes equal to or more than a threshold value.
