摘要： An electronic control apparatus includes a switching element; an ON-drive constant-current circuit supplying a constant current to the control terminal of the switching element thereby charging the control terminal of the switching element; an OFF-drive switching element discharging electrical charge from the control terminal of the switching element by being turned ON; and a control circuit adapted to control the ON-drive constant-current circuit and the OFF-drive switching element in response to a drive signal being inputted, thereby controlling the voltage of the control terminal of the switching element so as to drive the switching element. The control circuit controls the current control transistor based on the voltage of the current detection resistor and supplies the constant current to the control terminal of the switching element, and detects an abnormality in the ON-drive constant-current circuit based on the voltage of the current detection resistor.
