摘要： A load driving apparatus for driving a load with a constant current includes a shunt resistor and a driver circuit. A shunt current corresponding to the constant current flows though the shunt resistor. The driver circuit is connected to a first end of the shunt resistor to supply the constant current corresponding to the shunt current to the load. The driver circuit includes a reference voltage source for generating a predetermined reference voltage. The driver circuit adjusts the magnitude of the constant current by performing a feedback-control of the magnitude of the shunt current in such a manner that a first voltage corresponding to the reference voltage and a second voltage corresponding to a voltage at the first end of the shunt resistor become equal to each other.

摘要： A drive circuit for a switching element includes a constant-current control unit and a restriction unit. The constant-current control unit performs a constant-current control for charging an open/close control terminal of a switching element to be driven which is a voltage-controlled switching element with electric charge for turning on the switching element. The restriction unit restricts, to a reference voltage, a voltage between the open/close control terminal and a first end of a pair of ends of a current flow path of the switching element for a predetermined period following a start of the constant-current control within a charging process period during which the open/close control terminal is charged with the electric charge such that the switching element is turned on.

摘要： A drive device has a break circuit. The break circuit inputs phase-current values transferred from phase-current sensors mounted on an electrical path of a motor generator. A power switching element is equipped with a freewheel diode connected in parallel with each other. An inverter has pairs of the power switching elements. In each pair, the power switching element in a high voltage side and the power switching element in a low voltage side are connected in series. It is detected for the freewheel diode to be in a freewheel mode when a forward current flows in the freewheel diode. The break circuit detects the freewheel mode where the current flows in the freewheel diode in a lower arm when the phase-current value is not less than a predetermined threshold value. The break circuit detects the freewheel mode where the current flows in the freewheel diode in an upper arm when the phase-current value is not more than the threshold current value.

摘要： An electronic device that is capable of detecting an abnormal state such that a switching element is unable to be turned off in spite of a drive signal instructing turn-off of the switching element. The device includes a switching element that is driven by controlling a voltage on its control terminal, a drive circuit that controls the voltage on the control terminal of the switching element on the basis on an inputted drive signal to drive the switching element. In cases where there exists a current flowing through the switching element in spite of the drive signal instructing turn-off of the switching element, the drive circuit determines that the switching element is in an abnormal state, and cuts off supply of voltage from a drive power supply circuit to the control terminal of the switching element to thereby turn off the switching element.

摘要： An apparatus is provided to drive a voltage controlled switching element having a conduction control terminal. In the apparatus, it is determined whether or not voltage at the conduction control terminal is at a first voltage which is lower than a second voltage and which is equal to or more than a threshold voltage. The second voltage is a voltage provided when the switching element is in a normal on-state thereof. The threshold voltage is voltage at which the switching element is switched on. When it is determined that the voltage at the conduction control terminal is at the first voltage, the switching element is forcibly switched off.
