摘要： A control circuit for a semiconductor switching element includes a control terminal, a main electrode terminal, and a current sensing terminal, and controls the semiconductor switching element including a diode connected to the main electrode terminal or the current sensing terminal. The control circuit includes an overheat detection circuit, a current detection circuit, and an interruption circuit. The overheat detection circuit outputs an overheat detection signal when a temperature detected based on an output of the diode is equal to or higher than a predetermined set temperature. The current detection circuit outputs a current detection signal when an output value of the current sensing terminal is equal to or greater than a predetermined set current value. The interruption circuit turns off the semiconductor switching element when both the overheat detection signal from the overheat detection circuit and the current detection signal from the current detection circuit are input.

摘要： A semiconductor device for ignition performing a current control function and a self shut down function can include a pulse generating circuit, a switching circuit, and a current source circuit, the three circuits together generating a pulse current that discharges a capacitor in the self shut down process. This construction can serve to suppress oscillation of a collector current Ic of the output stage IGBT in the operating processes of the current control circuit and the self shut down circuit, thus preventing or minimizing the likelihood of the ignition plug from erroneous ignition. In addition, the discharge of the capacitor in a pulsed mode can allow for down-sizing of the capacitor, which can contribute to minimization of the semiconductor device.

摘要： In aspects of the invention, there is provided an igniting semiconductor device that can prevent burning of an IGBT or ignition coil, and erroneous ignition, even when reducing the size of a capacitor that generates a self-interrupting circuit time constant. In some aspects, a semiconductor device of the invention is configured of an IGBT and a current control circuit. The current control circuit can be configured of a first series circuit wherein an IGBT and a sense resistor are connected in series, a drive signal control circuit, and a self-interrupting circuit. At a time of abnormal operation, the self-interrupting circuit can output a voltage whose amplitude temporally drops in stages toward 0V to the drive signal control circuit. The drive signal control circuit can control the amplitude of a drive control signal so that the voltage across the sense resistor is equivalent to the output voltage of the self-interrupting circuit.

摘要： A main IGBT conducts or blocks a primary current flowing through the ignition coil in response to an input ignition control signal to generate a high voltage on the secondary side of the ignition coil. The main IGBT and a current limiter circuit are integrated in a monolithic silicon substrate of an insulating gate bipolar power transistor. The main IGBT has a collector and agate connected through a depletion IGBT forming part of a constant current circuit, and a resistor. When a voltage generated across the resistor becomes equal to or higher than a zener voltage, a zener diode leads this current to an emitter of the main IGBT.

摘要： An automotive ignition system lockup protection circuit utilizes a capacitor charging/discharging circuit to generate a periodic clock signal. A counter circuit activates an ignition coil deenergizing signal after a predetermined number of clock signal. The capacitor charges and discharges within a voltage reference window defined as the difference between a first reference voltage and a second larger reference voltage, wherein the first reference voltage is functionally related to a variable battery voltage and the second reference voltage is fixed and independent of battery voltage. The frequency of the periodic clock signal is modulated in accordance with the voltage reference window to thereby vary the lockup time in accordance with battery voltage. The capacitor charging and discharging current is adjustable to compensate for variations in the capacitor value and the entire circuit operates consistently over a temperature range typically required in an automotive application.
