摘要： A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which in addition to a control unit and a throttle actuator through which an opening angle of an engine throttle valve is adjusted so that the vehicle speed detected by a vehicle speed sensor coincides with a target cruise speed set by a vehicle driver through a set switch, a vehicle speed determining circuit is provided for determining whether the vehicle speed detected by the vehicle speed sensor exceeds a lowest speed limit above which the cruse control by the control unit and throttle actuator becomes effective. When the vehicle speed is below the lowest speed limit, the power supply to the throttle actuator is interrupted so that the cruise control by means of the throttle actuator is cancelled.

摘要： An output voltage monitoring circuit monitors an output voltage of a capacitor charging circuit. A first sample-and-hold circuit samples and holds a voltage of a connection point of a primary coil of a transformer and a switching transistor. A first monitoring comparator compares output of the first sample-and-hold circuit with a predetermined first reference voltage. When the output of the first sample-and-hold circuit exceeds the first reference voltage, a signal processor executes predetermined signal processing. The first sample-and-hold circuit starts a sampling period after a predetermined first time has elapsed after the switching transistor is turned OFF. When a voltage drop across a detection resistor reaches a third reference voltage, the first sample-and-hold circuit ends the sampling period.

摘要： In a driver circuit for a charge pump circuit capable of switching a step-up ratio, first and second oscillators oscillating at different frequencies are provided. The charge pump circuit is controlled by a control unit. The first oscillator outputs a first periodic signal required for the control unit to control the step-up action of the charge pump circuit. The second oscillator outputs a second periodic signal employed for a time measurement and having a frequency set lower than that of the first periodic signal. The control unit monitors the state of the driver circuit itself or the charge pump circuit and switches the step-up ratio of the charge pump circuit if a predetermined state continues for equal to or more than a predetermined period of time. The control unit turns on only the first oscillator when the step-up ratio of the charge pump circuit is lager than 1 to thereby perform the control of the step-up action and the time measurement based on the first periodic signal. On the other hand, when the step-up ratio is 1, the control unit turns on only the second oscillator and performs the time measurement based on the second periodic signal.

摘要： A voltage generating circuit includes a voltage generating unit which generates plural constant voltages, plural switches, a control signal generating unit and a decoding circuit. The switches select any one of the plural constant voltages generated from the voltage generating unit and outputs it from a voltage output terminal. The control signal generating unit generates plural control signals which are switched between a high level and a low level through trimming on plural fuse resistors. The decoding circuit controls the state of connection of the switches-according to the control signals. The reference voltage Vx output from the voltage output terminal is applied to an electric-current generating resistor through an operational amplifier and a transistor to generate a constant electric current.

摘要： A power supply apparatus switchably operates an LDO regulator and a DC/DC converter connected in parallel so as to control a battery voltage Vbat from a power supply at a constant output voltage VO. A detected voltage Vs at a shared output terminal shared by the LDO regulator and the DC/DC converter is input to a feedback input terminal and fed back to the LDO regulator and the DC/DC converter. In order to suppress an undershoot occurring when switching from the LDO regulator to the DC/DC converter, a timing signal generating unit supplies a capability switching timing signal to a pre-drive circuit and switches the control capability of the DC/DC converter from a low capability mode at startup to a high capability mode.
