摘要： An electronic system has IGBT, on driving FET and off driving FET connected with the gate of the IGBT, and a control circuit. The on driving FET in an on state supplies electric charge to the IGBT gate. The off driving FET in an on state releases the charge from the GET gate. The control circuit controls each of the on FETs according to a driving signal to be set in the on and off states every switching period of time and to control the voltage at the IGBT gate. When on-failure occurs in the on driving FET set in the on state so as to keep the on driving FET in the on state in spite of control of the control circuit, the control circuit controls a controlled element other than the off driving FET to set the IGBT in the off state.

摘要： A temperature detecting apparatus includes an integrated circuit that integrates an overheating detecting circuit, a breakage detecting circuit and a disabling circuit, and an element connection terminal connecting a temperature sensing element. The disabling circuit disables the breakage detecting circuit from detecting a breakage of wire when a voltage at the element connection exceeds a disabling threshold which is set higher than an overheating detection threshold and a breakage detection threshold. A predetermined voltage higher than the disabling threshold is applied to the element connection terminal when the temperature sensing element is not connected to the element connection terminal.

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： A switching device is provided which includes a switching element, and a current limiting circuit which limits current passing through the switching element when the current passing through the switching element exceeds a short-circuit detection threshold. The current limiting circuit limits the current passing through the switching element, until the current passing through the switching element becomes equal to or smaller than a current-limitation cancellation threshold which is smaller than the short-circuit detection threshold.
