    摘要： An inductive load is managed to reduce unnecessary induced electromagnetic radiation as caused by unwanted voltage and/or current fluctuations. The management is accomplished through combined current and voltage slew rate limiting of a transistor driving the inductive load. This management may be effected through a combination of analog and digital circuitry.

    摘要： In a method for triggering a DC motor through an integrated H-bridge circuit by using a control circuit and an apparatus for carrying out the method, a high-side transistor switch or a low-side transistor switch associated with each motor terminal, or both of the transistor switches, are each controlled or regulated to a conductive state by a respective guard circuit, if and as long as a potential at a motor terminal is or falls below a predetermined value. Each guard circuit has a biased transistor with a conductive state in which the associated transistor switches are made conducting through a current mirror.

    摘要： A symmetrical voltage divider whose tap is supplied with a reference voltage via a resistor is connected between the terminals of an inductive sensor. A diagnostic voltage is applied to the tap. Using evaluation devices, the diagnostic voltage is compared with two threshold values in a stationary state, and then sampled in the operational state, and a difference is calculated from the largest and smallest sampled, values and is compared with a third threshold value. Short circuits or line interruptions are detected from the comparison result and are displayed.

    摘要： The primary winding of an ignition coil is connected in series with an ignition switch that can be switched by a control circuit. A circuit including a capacitor, a resistor, and a diode is configured between the control terminal and the collector of the ignition switch. When the primary current is switched on, the capacitor discharge brings about a voltage reduction at the base of the ignition switch resulting in slowing down the trailing voltage edge at the collector of the ignition switch.

    摘要： An apparatus is described for regulating the flow of current through a load in which the flow of current is monitored in the form of a reference voltage by an analog input and a digital input of an arithmetic and logic unit. The voltage measured at the analog input is used to regulate the flow of current. The voltage measured at the digital input either as a low or as a high signal is used to switch off the flow of current when there is a low signal.

    摘要： The primary-side voltage profile of an ignition voltage is converted into an analog current through the use of a first regulating circuit, whose output voltage is compared with a first comparison voltage in a first comparator. The output voltage is compared with a second comparison voltage in a second comparator. A diagnostic signal for the ignition switch can be tapped at the output of the first comparator, and a measurement signal for the burning duration can be tapped at the output of the second comparator.

    摘要： A voltage monitoring device for monitoring two different supply voltages to be received by an electronic component. The monitoring device has a ratiometrically operating analog/digital converter, whose reference input is supplied with the larger supply voltage and whose measurement input is supplied with the smaller supply voltage. An output signal of the analog/digital converter is supplied to a window comparator in which the output signal is compared with predetermined limit values. A reset signal for the electronic component is produced if the output signal is greater than the upper limit value or less than the lower limit value.
