摘要： An analog switching circuit comprises an insulated-gate field-effect transistor (Q20) having two n-type input-side and outpu-side semiconductor regions (201, 202) and a p-type semiconductor substrate region 203, for controlling conductiveness between an input terminal (IN) and an output terminal (OUT) based on a gate potential. A surge pulse detecting circuit (1020), responsive to an electric potential (Vi) of the input terminal (IN), produces a detection signal of a surge pulse equivalent to a forward bias of a PN junction formed between the semiconductor substrate region (203) and the input-side semiconductor region (201). A substrate potential setting circuit (1010) varies an electric potential of the semiconductor substrate region (203) in response to the electric potential (Vi) of the input terminal (IN) when aby detection signal is produced. Furthermore, a gate potential control circuit (1030) varies the gate potential of the insulated-gate field-effect transistor (Q20) in the same direction as the electric potential of the semiconductor substrate region (203) when the detection signal is produced.

摘要： In an actuation circuit for a stepping motor, one switching element and its associated coil are connected at one connecting point, while the other switching element and its associated coil are connected at another connecting point. A pair of switching circuits and a pair of rectifying circuits are provided between two connecting points. When one of switching elements is changed from an ON condition to an OFF condition, the voltage difference between two connecting points allows the current to flow in a designated direction through the switching circuit and the rectifying circuit combined, thereby releasing the energy stored in the coils.

摘要： In a power supply apparatus, a switching circuit selectively applies one of an input voltage of a power converting circuit and an output voltage of the power converting circuit to a voltage reducing power supply circuit. When the input voltage is applied to the power converting circuit, the switching circuit selects this input voltage, so that the output voltage of the voltage reducing power supply circuit can quickly rise. Thereafter, when the output voltage of the power converting circuit exceeds this output voltage, the switching circuit selects the output voltage of the power converting circuit. As a result, a difference between the input voltage and the output voltage of the voltage reducing power supply circuit is decreased. Thus, a power loss is lowered and noise produced in the power converting circuit is suppressed.

摘要： An output MOS transistor and a current-detecting MOS transistor are connected commonly at their drains and gates. A gate voltage is fed to the gates of these transistors via signal lines. When the voltage of an output terminal is increased in response to excessive load current, a current-mirror circuit consisting of first and second transistors pulls in current from the signal line to reduce the gate voltage. Thus, the output current of output MOS transistor is limited within a predetermined level. Furthermore, a diode, provided in the signal line, produces a voltage drop equivalent to the base-emitter voltage of first transistor. By the function of this diode, the gate-source voltage of output MOS transistor is equalized with the gate-source voltage of current-detecting MOS transistor. As a result, the same operating point can be set for the output transistor and the current-detecting transistor.

摘要： A temperature detecting circuit detects the rise of ambient temperature, using a forward voltage drop across a diode. The temperature detecting circuit comprises a temperature detecting diode whose cathode is grounded, a first constant current supply device connected with the anode of the temperature detecting diode, for supplying a constant current Ia to the temperature-detecting diode, a rectifying diode whose cathode is connected with the anode of the temperature detecting diode, a second constant current supply device connected with the anode of the rectifying diode, for supplying a constant current Ib to the temperature-detecting diode, a comparator, and a transistor. When the voltage at the anode of the temperature-detecting diode is lower than a reference voltage, the comparator produces a high-level signal indicative of overheating. In response to this, the transistor shorts the anode of the rectifying diode to ground potential to supply the constant current Ib from the second constant current supply device directly to ground potential.
